9.5 Total Score
The Firefly 2 Vaporizer is Outstanding

The Firefly 2 delivers superior performance to the original Firefly and is packed in a smaller, lighter package. It feels solid, and the unique feature of having instant-heat on demand is addicting. A mobile app functionality has been added, and the device is now compatible with Herbs and Concentrates. It is impressive to carry around and produces best-in-class vapor quality. The Firefly 2 is as good as they get.

In-Depth Firefly 2 Review:

The Firefly 2 is much-anticipated pure convection Vaporizer by Firefly Vapor that was introduced as the successor of the original Firefly. The Firefly 2 has a whole bunch of super-useful features, the best one in my opinion, is the ability to Vape in short sessions. Unlike other vaporizers, the Firefly 2 has a small chamber (about 0.1-0.15 grams), and it delivers instant heat. This makes the Firefly 2 an outstanding “quick-hitter” vaporizer. You can activate and take a draw instantly, not having to vape all your material in one session. With most Vaporizers, once you activate, it takes around 30-45 seconds to heat up and then you have to vape all your herb (usually .3 grams) in one session. That’s great if you are hanging with friends and using together, but what happens when you are alone and just want two hits of your medicinal herbs? You will have to pack a whole chamber, as most vapes do not work well with a “half-empty” chamber. Not anymore! The Firefly 2 is capable of packing small amounts of herbs to use on demand, and there is virtually no ramp-up time. This makes the Firefly 2 one of the most efficient Vapes I ever tested.

The Firefly 2 is compatible with Dry Herb as well as Waxy Concentrates. The package includes 3 small Concentrate stainless steel Mesh Pads that you can place inside the bowl. Place your Dab on the little pad and close the magnetic cover. You will also need to change the settings on the mobile app to “Concentrate” in order to activate a slightly higher temp settings.

Firefly 2 Design:


This vape is a portable convection vaporizer made for dry herb, but also works with concentrates very well. This model is an upgrade/updated version of the original Firefly from years ago.

The Firefly 2 has been re-designed from the ground up and is smaller and much lighter than the original unit. In fact, Firefly 2 is 55% Lighter and 33% Smaller than the original version. The Firefly has a sporty yet elegant design and feel. The Firefly 2 consists of 2 main parts- the actual body of the Vaporizer, and the magnetic lid. The lid can easily snap on and off, exposing the chamber and the air-path. The lid has a small window allowing to see your chamber and herbs while you vape- another cool feature. With other vapes, you have to open the chamber to see if your herbs are fully exhausted. Nice to have a window that you can glance and know the situation in your chamber.

The mouthpiece is removable and allows for easy cleaning. The Firefly 2 Vaporizer users a USB 3.0 charging dock with an empty-to-full time of 45 minutes. The Dock is magnetic and you do not need to plug in any wires. Just place the Firefly 2 on the charging platform and it will charge.

The Firefly 2 features a Glass air path and keeps Vapor-Cool and Tasty. The Battery and efficiency have been improved and the Firefly 2 claims to have double the power of the original version. The battery is swappable and may be pulled out and replaced, or charged with an external charger. Firefly 2 included 2 batteries so you can always have one in the charger and one in your device. Each battery lasts between 40-80 draws, depending on heat settings and intensity.

The Firefly 2 is very well designed and was impressive to carry around and show people. It has an “iPhone” feel to it and buttons are “touch sensitive” not “pressure sensitive”. Everything about this Vaporizer feels luxurious, from the packaging to the smallest component everything was perfectly designed and placed.


The Firefly 2 heats up as you draw, meaning there are no lost components while the chamber is heating up. It allows you to inhale your material from room temperature to 400 degrees within seconds. This makes the Firefly 2 an extremely efficient device. With other Vapes you have to wait 30-45 seconds for the chamber to heat up, causing your material to “cook” while you are waiting for a draw. This makes using the same chamber for two sessions is not a pleasant task. But with the Firefly 2, there is no heat up, and this allows for multiple sessions with the same bowl.

The Firefly 2 is lighter, smaller, works better than the previous model. One of the most important things to know about how the Firefly 2 works is that it uses small amounts at a time, 0.1g maybe 0.15g.

The Firefly 2 features a Borosilicate Glass Vapor Path to ensure the purest flavors and aroma from Dry Herb or Concentrate. The heating chamber has 55 Laser-drilled Micro Jets that evenly distributes convection heat through your material. Unlike other Vapes, the herb you use does not need to be finely ground, and can be broken up with your hands.

Firefly 2 Vapor Quality:

The original Firefly was known for its excellent Vapor Quality and the Firefly 2 is no exception. The Vapor is smooth and consistent, both with Herb and Concentrates. The Borosilicate Glass Vapor Path and Glass chamber are doing a great job in keeping the vapor clean and aromatic.

Many other portable vapes have the mouthpiece sitting on top of the heating element, not allowing the vapor to cool down. This causes harsh vapor and a hot mouthpiece- not fun. Since the Firefly design is different and the chamber is located away from the mouthpiece, the vapor was never warm, always cool and smooth. The mouthpiece never got hot.

Overall the Firefly 2 is outstanding in terms of performance and vapor quality. It is in par with the best Vapes in the industry and is a leader when it comes to innovation and unique features. The Vapor quality is good enough to impress a professional Vaper (I consider myself one) and to amaze a beginner. Some of my friends and family that tried the Firefly 2 said it is the first Dry Herb vape that truly delivers beyond their expectations. Quality sure has a price. And it is slightly over $300.

But the Firefly 2 is a smart investment and over time will make you use less material and save on your buds. I explain all about that in my Firefly 2 Efficiency article.

Smartphone App:

The most exciting upgrade to the Firefly 2 is the addition of a mobile app, where you can set the temperature, and easily switch between Dry Herb or Concentrate modes. You can select between a few heat levels for herb, and one mode for concentrate. Concentrate mode is the strongest heat, and should not be used with herb as it may burn them. The app allows control on other device settings for a truly customized experience. The FireFly 2 is Bluetooth connected and the app is available for iOS or Android smartphones.

UPDATE 11/1/2016: Firefly updated the smartphone app with a Boost feature that allows fine tuning of the heating algorithm up or down. This basically makes the heating profile more aggressive and will  good results if you want to increase the vapor production or just want more heat. Using this new feature added another layer of control and made a noticeable difference in overall performance.

The Vape Guide Recommends the Firefly 2 for:

The Firefly is known to have superior flavor and the fastest heat up time in the industry. It is a perfect Vaporizer for you if you like using small amounts of herb at a time, and take breaks between draws. Most Herb Vaporizers are “session” Vapes, meaning you click a button to start a session and at the end of this session your herb is fully vaporized and you need to reload the chamber. The Firefly 2 is more of a “One-Hit-At-A-Time” device and will allow pauses with the same material in the chamber.

Where to buy the Firefly 2

Buying directly from  Firefly Vapor is the safest option and will ensure that you get the full warranty.

Firefly vapor offers free US shipping and the Firefly 2 comes with a 2-year limited warranty.


 Is it worth the price tag?

Definitely. In my opnion, the Firefly 2 is the Best Portable Vaporizer available today (view full list here). If you are serious about your vaping, the Firefly is a necessary tool in your arsenal. It quickly became my favorite vaporizer, and if judging by the Firefly 1 life expectancy, I’m sure it will perform well for years to come. Sure you can buy a $150 vape that will last for around a year, but the FireFly 2 is timeless and will pay for it’s on investment in terms of material efficiency.

    I give the Firefly 2 a 9.8 (Glass and Scientific grade metal). I got it last Friday. I have used it everyday. It is a great vape. The metal and glass build, the glass window, the flavor, very powerful, the dock, easy to clean and when cleaned its like brand new every time, no filters to clean or replace, it comes with 2 batteries a cleaning kit, the unboxing is top rate, the warranty is great, the app is a very good feature, the size is very good, excellent portability and the convection oven and dynamic heating is like no other vaporizer very stealth.

    The batteries do have to be changed sometimes in midst of a long session. This would be a major negative but the Firefly 2 does come with 2 batteries. It can be awkward to hold when touching both sense buttons. This would also be a major negative, but it can be changed via the app, and its not that difficult of a hurdle to get used to. The downside to the app is it needs to be reconnected each time, or it will be set to factory settings. I find this annoying because I need to keep my phone close.

    I am retiring some great vapes in favor of the Firefly 2, My Magic Flight (9.6), My Arizer Air (9.6), and My Arizer Solo. I will still use my Arizer Extreme Q Desktop unit, but not as much the Firefly 2 is an extremely powerful device. I would also like to warn you to take it slow while getting used to your Firefly 2, it is a very powerful vaporizer.

    I have learned via the vapes I have purchased that, although the plastics get top tier reviews fo vapes like the Volcano, Plenty, Mighty, Crafty, Pax, and others made with plastic. I have learned that there is a major taste difference, and the taste from these plastic vapes, is coming from the plastic and rubber washers. This is something that has been ignored by Bud and many other critics.

    I would like to say I am on a crusade to make my fellow Vapers aware the plastic vapes are marketed extremely well, the initial results are great, but the long term results go south pretty quickly.

    The Firefly for the most part will take the place of my Solo (Metal and Glass), Air (Metal and Glass), Magic Flight (Wood, Metal Acrylic) and my desktop The Arizer Extreme Q (Glass and Glass!) desktop unit. Please stay away from the highly rated and marketed vapes made of plastic and rubber, its toxic. The performance might be super duper but plastic and rubber when heated and inhaled into your lungs cant be a good thing. Glass and Metal is pure vaping.

    Firefly2 has amazing capabilities and is so customizable! I love that I can put concentrates or flower in the bowl and have totally different experiences and get amazing flavor each time! With flower, I’ve found that you truly get the whole plant experience, getting all those terpenes and flavors with each draw. With concentrates, the flavor is still incredible and I find that this works best for me if I’m going on a hike or somewhere that I don’t want to worry about reloading my Firefly2 and it lasts so long! Its amazing how much this vaporizer customizes to fit your lifestyle, health needs, consumption, and style! I truly love this vaporizer and it’s really changed the way I consume for the better <3

    The Firefly2 vaporizer works like a charm. It is a high quality product that is compact with a sleek polished look. It is easy to use, and easy to clean up. Convection heating instead of burning preserves the true essence of the herb allowing for the intake of the full body flavor of your favorite herbs. The efficient and long lasting battery recharges quickly and is ready to use in under 45-minutes. The high tech glass heating and supply system provides a smooth chemical free vapor path. The Firefly2 has an APP to manage heating profiles for different densities and qualities of herb. It is economical and fun and one of the best portable vaporizers on the market.

    I am impressed BUT you choose a deal killer when you decided that the customer MUST have a smart phone handy to put it on high for concentrates…. sorry but I do not keep cancer causing devices such as smart phones handy, not to mention what a great way for the feds to profile you by running a smart phone app like this…….
