Firefly 2 vs Haze V3 Portable Vaporizer Comparison

The Haze v3 and the Firefly 2 are both great options for anyone considering a portable vaporizer, but these two units have some very distinct differences in their design and operation.

Both of these vaporizers are innovative in their own rights and have brought new and exciting ideas and concepts to the market. Both of these vaporizers also offer great vapor quality and efficiency, replaceable batteries, and easy maintenance.

What we’re going to do in this comparison is show you where they are similar, where they are different, and in the end which one would fit you better. The comparison will be broken down into the following categories:

  • Ease of Use
  • Temperature Control
  • Vapor Quality and Efficiency
  • Pocketability and Discreteness
  • Battery Life
  • Warranty

Alright, let’s get into the Firefly 2 vs Haze V3 vaporizer comparison!

Ease of Use

This category covers how easy it is to operate these vaporizers. Every vaporizer is used differently, some offer super straight forward designs, while others take some instruction and patience in learning how to use them effectively.

Here we are going to see how easily it is to operate the Firefly 2 and the Haze v3 respectively.

Ease of use with the Firefly 2

To begin with, the Firefly 2 uses a smartphone app to adjust your heating profile, adjust which touch capacitive button activates the heater, and to see your battery level.

Navigating through the app is pretty straight forward as everything is labeled clearly and understandably. There’s no technical lingo or anything in app. Anyone can open the app and immediately know how to adjust the heating profile or do whatever they desire with it.

Firefly 2 Smartphone App

The only issues I have had with it was Bluetooth connectivity in the beginning, but since then those issues have been resolved. In general, closing and re-opening the app has remedied a lot of the issues I had with getting my Firefly 2 to pair to my smartphone.

Personally, I wish you could use the touch capacitive buttons in some way to cycle through the heating profiles instead of having to pull out your phone, but it isn’t a deal breaker for me.

When you are preparing your flower for use with the Firefly 2, you don’t have to do anything that you normally wouldn’t when preparing a session. The grind from a normal 4 piece grinder is actually the preferred  grind consistency for the Firefly 2, as opposed to traditional conduction units that usually require their users to grind very finely for optimal performance.

Without diving too much into the vapor quality of the Firefly 2 (we get to that later), I do have to address something about it from an ease of use standpoint. Since the Firefly 2 is a 100% convection vaporizer, you have to be mindful of how much air you are drawing through the unit, and how fast you are drawing said air.

It takes a bit for new users to get the hang of hitting the Firefly 2; it isn’t hard, but it’s just a different experience as compared to other portable vaporizers.

You just have to take long and slow draws – about 15-30 seconds for the best results. Unless you’re an experienced vaporist, don’t expect to pick up the Firefly 2 and get immediate good results.

Also, you do have to stir the Firefly 2 for the best results at least once per bowl. I typically just use my finger to stir the oven, and the vapor path gives you a good amount of surface area to mix up the material without spilling it all over the place and making a mess or losing precious material.

Regular maintenance with the Firefly 2 is a quick and painless process unlike a lot of vapes on the market. A simple wipe down with some kind of cloth damped in isopropyl alcohol is all you need to clean this vaporizer in under 30 seconds.

If you don’t stay on top of cleaning it, the process can take longer as the buildup is harder to wipe off, but if you clean it every 5-10 ovens the unit stays pristine.

Ease of Use with the Haze v3

As with most vaporizers on the market today, the Haze v3 has all of its controls for operation on the device itself. The only actual button the vape has is the temperature control button on the top of the device.

The way you power this device on is by rotating the top piece of vaporizer as shown below.

Haze v3 Oven Markings

We haven’t stated this yet, but the Haze v3 has 2 separate ovens that you can pack simultaneously. The way you control which oven you are vaping from is dependent on which direction you rotate the top of the Haze v3.

Each oven is marked with a different symbol, one oven has a fully colored in circle, and the other is the outline of a circle.

Haze v3 Ovens

Once you’ve selected which oven you want to vape from, you can start cycling through the 4 temperatures with the button residing on the top of the unit.

The user also has a choice of two mouthpieces or stems. You have a metal stem and a glass stem that are more or less the same.

I personally prefer glass as I find it the most comfortable material to rest my lips on, but it’s really subjective and all personal preference.  I like the metal one almost just as much and it really doesn’t make any difference in actual performance.

Haze v3 with Metal Mouthpiece

The fact that all of the unit’s operation is on the device itself is good for someone who doesn’t want to be tethered to their smartphone just to use their vaporizer. Having to use your phone like with the Firefly 2 is one of those things I don’t mind, but I am well aware there is a percentage of people who would rather not have to deal with their phone to adjust their temperature settings or just basic unit operation in general.

When you are getting ready to use the Haze v3, I found it best to grind your material as finely as possible. The Haze v3 is primarily a conduction vaporizer, and as such it performs best when there’s a lot of available surface area for the walls of the oven to vaporize the active compounds on the flower.

I found the Haze v3 works with most draw types. In my experience, 15 second medium to slow draws worked well and produced good vapor. As with most portable vaporizers, you can’t draw super aggressively from it and expect it to keep up with you.

Stirring with the Haze v3 is something I found unnecessary. So long as I ground my material finely, I had no issues evenly vaporizing an oven without stirring when using the Haze v3.

Maintenance with the Haze v3 is really easy just like the Firefly 2, but it does take a little longer.

The extent of cleaning the Haze v3 is soaking a cotton swab with isopropyl alcohol and running it through the vapor path where the stem of your choice is usually stored as this vapor path accumulates oil and will make your stem stick if you don’t stay on top of it!

Likewise, cotton swabbing the ovens when no screen is installed helps clean up any residual oil that may be coating the oven inside the unit. Finely wiping down the stem with a paper towel dampened with isopropyl alcohol is a good idea as well.

It may seem like a lot, but it really isn’t in practice. I get my Haze v3 fully cleaned in under 10 minutes, and maintenance is something I have been doing once or twice a month. You can get away with longer, but I found my stems started to get hard to pull out due to the buildup of oil in the vapor path.

Which Design is Easier to Use?

I would say the Haze v3 by a slight margin. Most users are going to be able to pick up the Haze v3 and immediately get good results.

Every time I hand someone new the Haze v3, they never have issues getting good draws right from the get-go. The Firefly 2 takes a little effort on the user’s part to achieve a good vapor hit.

Also, with the Haze you don’t have to bother with using your phone to adjust the temperature, which some people may find a big plus.

Temperature Control

This section will go over the temperature settings of these vapes. Both of these are much different in how they handle adjusting temperatures.

The Firefly 2’s Temperature Control

Unlike the Haze v3, you are unable to adjust the Firefly 2’s heating profile on the fly without pulling your smartphone out and opening the app.

Firefly 2 Temperature Control via Smartphone App

From the smartphone app you have the ability of cycling through 5 different heat profiles for dry herb, and 1 for concentrates. The heat profiles are as follows:

  • Low – 340°F
  • Medium Low – 360°F
  • Medium – 380°F
  • Medium High – 400°F
  • High – 420°F
  • Concentrates – 500°F

This is a good temperature spectrum and covers most of the areas people will want to vape at.

The Haze v3’s Temperature Control

A big pro for this unit is the fact that all of the temperature control is done with the button on the top of the unit. You simply tap the button to cycle through the temperature settings.

The 4 LED lights on the front of the unit will glow to designate what temperature you are on. If you are at temperature level 2, two LED’s will glow on the front, and so on.

Haze v3 Temperature Control

The temperature settings are as follows:

  • Temperature 1: 365 °F
  • Temperature 2: 385 °F
  • Temperature 3: 395 °F
  • Temperature 4: 420 °F

Overall, the Haze v3 covers a good temperature spectrum for both dry herbs and concentrates, and it will allow you to appreciate the flavorful and smooth lower temperature vapor as well as fully extract all of the active compounds out with the higher temperature settings.

Who has the best temperature control?

If we’re talking just temperature spectrum, I would narrowly hand it to the Firefly 2 as it does offer two more temperature presets: an extra one for dry herb, and one specifically for concentrates.

With that said, if you would rather not have to use a smartphone to adjust your temperature, the Haze v3 may nudge out the win for you personally. In my opinion, the Firefly 2 just barely defeated the Haze v3 in this department.

Vapor Quality and Efficiency

I am happy to say that the Firefly 2 and the Haze v3 both exceed my expectations for vapor quality and efficiency.

There are some key differences when comparing these two units though. The Firefly 2 is a convection vaporizer and the Haze v3 is primarily a conduction vaporizer.

Both of these units produce different experiences, and this section of the comparison is going to compare and contrast each unit’s vapor quality and efficiency.

The Firefly 2’s Vapor Quality and Efficiency

In my opinion, the Firefly 2 offers the best vapor quality out of any portable vaporizer I have ever had the pleasure of using. The Firefly 2 delivers its outstanding vapor quality via its on-demand 100% convection heating system.

The vapor from the Firefly 2 will show you the true effects and flavors of any material you put in it, letting you truly appreciate higher quality flowers and concentrates.

Firefly 2 and High Quality Dried Cannabis Flowers

When you first pick up the Firefly 2, you may not get really good results out of the gate and that’s because you have to operate this vape a little differently as opposed to traditional conduction heating vaporizers.

What the Firefly 2 is doing is heating the air itself and then drawing that hot air over your herb or concentrate, allowing it to gently vaporize your material. This is different from conduction vaporizers in which the material is in direct contact with the oven and gets heated that way.

You have to be mindful of the amount of air you are drawing through the unit because the air you’re drawing through the vape is what is doing the work and producing vapor.

As we stated before, this is an on-demand heating vape. This is part of the reason why the Firefly 2’s vapor is so consistent and flavorful. The unit is only heating your material when you engage the heater.

What this means is that you are not losing any volatile compounds like terpenes like you do when the Haze v3 is getting to optimal temperature.

I really liked the vapor from the Medium heating profile up to the High heating profile. The 380°F-420°F temperature range on this device is outstanding.

Even at the High heating profile, the vapor is very flavorful, smooth and potent. Typically when I exceed 400°F  on a portable vape I find the experience really uncomfortable and unenjoyable. The Firefly 2 is one of the only vapes that I enjoy going past 400°F on.

The Firefly 2 happens to be one of the most efficient vaporizers in my collection as well. I only need about .1 of coarsely ground flower to get a good extraction with the Firefly 2.

With that said, you do need to stir the Firefly 2 at least once per bowl to achieve an even extraction. If you fail to stir the oven, the material won’t be evenly vaporized.

The Firefly 2 excels with concentrates; in fact, I would say this is the best way to appreciate high quality oil and melty hash.

You will truly experience the extracted cannabinoid and terpene profiles in their purest form. You’ll notice subtle flavors and effects that you haven’t noticed before with other vaporization mediums for concentrates.

The Haze v3’s Vapor Quality and Efficiency

Even though the Haze V3 is a conduction unit, that is not to say it doesn’t have outstanding vapor quality compared to the Firefly 2. At the same time, it is not hard to understand why the Firefly 2 would have better vapor quality.

The Haze V3 is a conduction session vaporizer, which means this is the type of vape that you sit down and finish a bowl in one sitting as opposed to hitting it once or twice and putting it down.

Haze v3 Vapor Quality

The Haze v3 has 4 ways you can pack the two ovens:

You have the option of using the conduction screens, convection screens, dry herb can, and the oil can.

All of these methods have their own respective pros and cons and we’ll break it down here. There are 3 ways you can vaporize dry herbs, and one way to vaporize concentrates.

Convection Screen

Haze v3 Convection Screen


  • Best flavor
  • Slightly smoother


  • Worst vapor production

Conduction Screen

Haze v3 Conduction Screen


  • Quickest extraction
  • Greatest vapor production.


  • Hottest and harshest packing method
  • Worst flavor

Dry Herb Can

Haze v3 Dry Herb Can


  • Can pack the most material
  • Best compromise of flavor and vapor production
  • Best solution for on the go


  • Can is hot after use

Oil and Concentrate Can

Haze v3 Concentrate Can


  • Great flavor
  • Great vapor production
  • Can hold large amount of concentrate
  • Easy to clean


  • Can is hot after use

I use every method of loading the Haze v3 as I find them all enjoyable and I like the experience they all offer. It’s really subjective as to what you prefer when using the Haze v3 since they are all solid choices but have their own pros and cons.

There isn’t much of a draw technique here either. You just draw air from the Haze v3 at a slow to medium draw speed for a few seconds. Vapor production is pretty instant after the initial first few hits of an oven, so you don’t have to draw from the unit long unless you want a substantially large vapor hit.

I found temperature 1-3 to be my preferred settings for dry herb, and temperature 4 for concentrates. Temperature 4 I found too harsh for dry herb, but I have passed it to friends who didn’t mind, so it really comes down to what you prefer.

You can load about .2 of finely ground material respectively into each oven, and the Haze v3 does an excellent job at fully extracting all of the active compounds in the material. The conduction screen especially does an amazing job at ensuring you’re getting every last bit out of your flower.

The Haze v3 is excellent with concentrates. You can load large and small amounts alike and get amazing results.

The Firefly 2 doesn’t work well with larger amounts of concentrates, but the Haze v3 usually does not have any issue effectively vaporizing larger amounts of oil.

The flavor is also outstanding, but not quite like the Firefly 2’s.

Haze v3 and Concentrates

Who has the best Vapor Quality and Efficiency?

The winner is clearly the Firefly 2. The Firefly 2’s convection heating offers the best vapor quality out of any portable vaporizer I have put it against.

If vapor quality and efficiency is your primary concern, the Firefly 2 is probably what you are looking for!

Not that the Haze is bad in any way as we already talked about, but it doesn’t quite stack up to the Firefly 2 in this particular category.

Pocketability and Discreteness

The pocketability and discreteness category will go over how easy these units are to transport on the go and how discrete their designs are for public use.

Pocketability and Discreteness of the Firefly 2

The Firefly 2 is 55% lighter and 33% lighter than the original Firefly. The small and sleek design fits very comfortably in the hand and can effortlessly be stored in a pocket or a bag. It’s a really easy device for anyone to transport.

Firefly 2 in Hand

The actual design of the Firefly 2 is pretty obscure and not many people will even know what is your hand. Depending on how you conceal the unit with your hand, it can be viable for public use at your own discretion as it doesn’t completely scream to the world that you’re consuming cannabis.

Pocketability and Discreteness of the Haze v3

The Haze v3 is also sporting a really small and compact design. It also fits well in the hand and is stored easily in a pocket or a bag.

Haze v3 in hand

The design of the Haze v3 pretty much resembles a small flask and is actually pretty obscure when being held. The Haze v3 is also another vape that is feasible for public use, as like the Firefly 2 it doesn’t exactly scream cannabis paraphernalia.

Which Vape is More Pocketable and Discrete?

I would say they are even in this respect. Both designs are small and easy to transport, as well as being comfortable in the hand.

While I personally like to vape away from the public eye in a more secluded area, you can get away with using these devices in public if you desire.

Battery Life

The battery life section of this comparison is going to compare how long each battery lasts, how they are charged, and if they are replaceable.

The Firefly 2’s Battery Life

Depending on what heat profile you prefer, I found myself getting anywhere from 5-8 bowls per battery. The higher heat profiles will deplete your battery faster, and the lower profiles will preserve your charge.

The Firefly 2 also comes with an extra replaceable 7.4V Lithium-Ion battery so you can extend your battery life, or even replace a battery that isn’t a holding a charge quite like it used to over a few months of heavy use.

The fact you won’t ever have to send your Firefly 2 in to get its battery changed is a big pro! Vapes like the Crafty require you to send your vape into Storz and Bickel to replace the batteries, which is a hassle when vaporizers like the Firefly 2 let the user do it themselves.

Firefly 2 Replaceable Batteries

I don’t really like having to use the charging dock. It does charge the vape really fast though, so it’s hard for me to be upset about it.

I personally prefer direct charging or an external charger like the Haze v3’s that lets you charge multiple batteries at once, something Firefly vapor charges extra for.

Firefly 2 Charging Dock and Charging Pins

Getting back to the fast charging, you have most of your battery available after only sitting on the charger for 20 minutes. After another 20, it should be fully charged. That is a total charge time of only about 40 minutes!

The Haze v3’s Battery Life

I found the Haze v3 offered about an hour of usage per battery, or about 4 sessions. Using the extra replaceable 18650 battery will double your effective battery life.

The haze v3 comes with two 3.7V 18650 3200mAh Lithium-Ion batteries. Like the Firefly 2, this allows the users to service their own battery if the battery fails in their unit or begins to not hold its charge as long anymore.

This makes the Haze a better value than other portable vapes overall.

Haze v3 replaceable batteries

Unlike the Firefly 2, these batteries do take a bit to fully charge. About 2 and a half hours was the time I had to wait for my batteries to charge.


Who has the Best Battery Life?

I would call it a tie here again. Both units offer replaceable batteries and effectively have almost limitless battery life if you are willing to buy extra ones.


This section will briefly go over the warranties on each of these units.

The Firefly 2’s Warranty

The Firefly 2 offers a 2 year warranty on factory defects and and flaws in the devices workmanship. Personally, I would like to see a longer warranty, especially when compared to the Haze V3’s lengthy warranty.

The Haze V3’s Warranty

Haze Technologies offers a 10 year warranty. The Warranty covers any defects in material or workmanship under intended use. The Warranty covers the unit only, and none of the accessories.

Who has the best warranty?

I would definitely hand it to the Haze v3. Standing behind your product for 10 years says a lot about the unit and the company.

The peace of mind of being covered for such a lengthy time period is great for a vape carrying a relatively hefty price tag for most people.

Conclusion: Which Vape is Best for you, the Firefly 2 or the Crafty?

What is that you are looking for? Each of these units offers something different with both having small portable designs and replaceable batteries.

The Firefly 2 is a great vape for home use, and light on the go use. If you wish to travel with the Firefly 2, you’ll need to bring something to store ground flower in or else you’ll be left with a single oven. For some people this may be all they need, but for others it won’t be enough.

If you’re going to be finding yourself primarily at home and are looking for the best vapor quality in a handheld form factor, the Firefly 2 is what you are looking for.

That’s not to say you can’t bring the Firefly 2 on the go, it just doesn’t work as well for me since I like carrying as little as possible with me and carrying a grinder around is something I don’t like to do.

Firefly 2 New Yorker Hotel

The Haze v3 has a better solution for on the go use. Without even mentioning the dry herb cans, the Haze v3 offers its users 2 ovens to load with materials of your choice. These 2 ovens are more than enough for me if I’m going to be away from home for a few hours and I am only using the haze V3 by myself.

You can pick up an additional 2 dry herb cans from the Haze website for about $15, and these make on the go use even easier. I would much rather carry around 4 of the dry herb cans loaded with herb rather than a bulky grinder or a big bag of cannabis flowers.

If you plan on being out of the house a lot and want something that will serve you best for that purpose, grab the Haze V3.

Haze V3 and a 2015 Red Elvis Bronto by Elbo

In closing, I’ll say this: both are excellent options, however I found the Haze v3 better for on the go use as the dry herb cans make transporting possibly illegal materials a lot easier. Also, its just easier overall to pop a can in rather than loading an oven while on the go.

The Firefly 2 is amazing for someone who is going to be at home primarily and is looking for the best vapor quality out of any portable. It’s just easier to load and use the Firefly 2 at home rather than on the go in my opinion.

At the end of the day, you cannot go wrong with either of these units. It just comes down to your personal preference and how you will be using your vape.
