In Depth Firefly 2 Review:

Firefly 2: The Quick Why

This Firefly 2 review touches upon the highly-anticipated Firefly 2, a pure convection Vaporizer made by Firefly Vapor that was introduced and touted as the successor to the Firefly. The Firefly 2 vape has a slew of highly functional features; the most useful being the ability to vape in short sessions. Unlike other handheld vaporizers, the Firefly 2 has a small chamber (about 0.1-0.15 grams) and delivers instant heat. This makes the Firefly 2 an outstanding “quick-hitter” vaporizer.


For those individuals who once enjoyed smoking from a bowl (in a past life, of course), the Firefly2 is the perfect vape equivalent as both the size of the chamber, and its rapid heat-up speed allow for simple loading and unloading of small quantities of dry herb that never go to waste. As many people that are new to the world of vaping–and even more seasoned vapers–are quite concerned regarding wasting their buds, these features cannot be overlooked.

The Firefly 2 makes it easy to pull a quick hit without the necessary heat-up times required by most of the vapes on today’s market. Those of us who just want to grab a hit or two from their vape without “pre-heating the oven” will certainly appreciate the Firefly 2’s speed and efficiency. The Firefly2 is an excellent vape for a veteran vaper, but likely the best vape for beginners.


You can activate and draw from your vape instantly, which also comes in handy because you do not have to vape all your material in one session. Most vaporizers take roughly 30-45 seconds to heat up once they are activated, and only allow the user to vaporize all the contents that they have loaded into the heating chamber (around .3 grams)–or risk wasting the unused material.

No Waste

The need to cash your entire chamber in one sitting is fine if you are vaporizing with friends or guests, but what if you just want a couple hits of your medicinal marijuana? You would have to pack a brand new chamber, as most vapes do not work well with a “half-empty” or “half-full” chamber. Not anymore! The Firefly 2 is capable of packing small amounts of herb to use on demand, and there is virtually no start-up time. This makes the Firefly 2 one of the most efficient vapes I have ever tested, and the best vaporizer for weed.

The Firefly 2’s illuminated chamber is visible through a clever looking glass that lets the user see the vaporization in progress.

The Firefly 2 is compatible with Dry Herbs, as well as Waxy Concentrates. The package includes 3 small concentrate stainless steel mesh pads that you can place inside the bowl for filtration of larger particles. Simply place your dab on the pad inside the chamber and close the magnetic cover. You will also need to change the settings on the mobile app to “Concentrate” in order to activate the higher temperature settings needed to vaporize waxy concentrates.

This concentrates feature, along with the Firefly 2 smartphone app makes it easy to achieve the ideal vaping temperature for vaping concentrates without the hassle of a manual temperature control. And, as we already know, the Firefly 2 is ideal when it comes to rapidly heating up to high temperatures–so you do not need to be concerned that you will need to wait a long period of time before vaping your concentrates nor dry herb.

Firefly 2 Design

The Firefly 2’s new sleek design was imagined from the ground up and is more compact and much lighter than the original Firefly. In fact, Firefly 2 is 55% lighter and 33% smaller than its predecessor. The original Firefly has a sporty, yet elegant design. The Firefly 2 consists mainly of two parts – the actual body of the vaporizer, as well as the magnetic lid. The lid can easily snap on and off, exposing the chamber and the air-path. It also has a small window that allows you to see your chamber and its contents while you vape – another genius feature.

With the other vapes on the market, you have to open the chamber to see if your herbs are fully exhausted. It is an ingenious feature which enables you to take a glance at your vaporizer and immediately know whether or not you have to replace what you have loaded or not. Plus, the ability to see the dry herb inside the illuminated chamber contributes to that feeling of smoking from a pipe–but, of course, without the health risks associated with smoking.

The Firefly 2 has a brushed aluminum exterior shell and, of course, the small transparent viewing portal where you can watch your marijuana vaping.

The Firefly 2 mouthpiece is completely removable for easier cleaning. The Firefly 2 Vaporizer uses a USB 3.0 charging dock with an empty-to-full time of 45 minutes. The dock is magnetic and does not require the use of any wires. Simply place the Firefly 2 on its charging platform and voilà! You’re all set up!

The Firefly 2 features a glass air path that keeps the vapor at a low temperature for a more palatable vaping experience. The Firefly 2 battery and efficiency have also been improved, and the Firefly 2 claims to have double the power capabilities when compared to the original. The battery is swappable and may be pulled out and replaced, or charged with an external charger. The Firefly 2 includes two batteries, so you can always be charging one while one powers the device. Each battery will last between 40-80 draws, depending on heat settings and intensity.

The Firefly 2 is an impeccably designed piece of machinery that will instantly leave a lasting impression on even the most seasoned veterans in the handheld vaporizer game. It has several features which distinguish it from the other major players on the vaporizer market, so it is not a direct competitor of too many vapes out right now. Its design and functionality set it apart and deem it a worthy addition to your collection.

The buttons are “touch sensitive” and therefore rely on body heat emitted by your fingertips to respond to commands, instead of “pressure sensitive” which allows you to use a stylus or other tools to input commands into your vaporizer. Everything about this vaporizer implies cutting edge; from the packaging, the instructions, the sleek design, or the cool new chamber window. The Firefly 2 is the complete package for the newbie vaper or the more experienced veterans on the market for a cool new toy.

Firefly 2: Performance

The Firefly 2 heats up while you draw from it, meaning that nothing is lost or wasted while you wait for the chamber to heat up to your desired temperature. It allows you to inhale your material anywhere from room temperature to 400 degrees, within seconds. This makes the Firefly 2 one of the most efficient handheld vaporizers on the market today.

With other vapes featuring a 30-45 second waiting period for the chamber to fully heat up, which results in some of your material burning away before you even begin your session. Which makes using the same vaporizer for two consecutive sessions an unpleasant experience. However, with the Firefly 2, there is virtually no heat-up time, which sets the stage for multiple sessions with the same packed chamber.

The Firefly 2 features a Borosilicate Glass Vapor Path to ensure the purest flavors and aromas derivable from dry herbs and concentrates alike. The heating chamber has 55 laser-drilled micro-jets that evenly distribute 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. This is because the heating chamber and machine itself are so efficient, that increasing the surface area exposed to the heat will make no discernible difference in the quality of your vapor.

Firefly 2 Vapor Quality

The original Firefly was known for its excellent vapor quality and the Firefly 2 has followed suit. The vapor is smooth and consistent, both with herbs and concentrates. The Borosilicate Glass Vapor Path and glass chamber do a phenomenal job at keeping the vapor clean and aromatic. Many other portable vaporizers feature a mouthpiece sitting on top of the heating element, which allows very little time and/or space for the vapor to cool down before arriving to your lips. This usually results in harsh vapor and a hot-to-the-touch mouthpiece…not ideal.

The Borosilicate Glass Vapor Path does a great job at preserving the natural flavor and aroma of the herb or extract.

Since the Firefly design is different and the chamber is located farther away from the mouthpiece, the vapor is never warm, always cool and smooth. Yet another clear advantage from the competition. The Firefly 2 has one of the highest vapor qualities that I have ever observed in a handheld device. Many portable convection vaporizers struggle to achieve high-quality vapor, due to small and often shoddily made parts. The Firefly 2 achieves this through the state-of-the-art glass design and pathway, all while being easy to use and remaining cool on the outside due to its aluminum alloy design.

The Firefly 2 is a top competitor for the best weed vaporizer in terms of vapor quality and efficiency, as it lets the user heat up the bud in the chamber within seconds – while eliminating waste.

Something important to note about the quality of the vapor is that it took me a couple of days tinkering around with the settings and with my dry herbs to find the best combination of factors to facilitate the best and most efficient vapor. This meant reading and rereading the instruction manual to get a better understanding of how the machine works. One of the reasons that grinding your herbs is not encouraged with this device, is because if the herbs are ground too finely, they can find their way into the mouthpiece through the mesh filtration. This is unsavory for obvious reasons, so it can be avoided if you stick to larger buds and crushing your herbs with your fingers instead of the use of a grinder.

Overall, the Firefly 2 is outstanding in terms of performance, vapor quality and efficiency. It is most certainly on par with the best handheld vaporizers on the market today, and is a leader when it comes to innovation via unique features. The vapor quality is good enough to impress one of the game’s most experienced vapor heads -myself included- and would definitely knock the socks off of a novice. Some of my friends and family have tried the Firefly 2 said it is the first dry herb vaporizer that truly delivered more than what they expected. Quality always has a price, and in this case it is just over $300.

Though, I would assert that the Firefly 2 is a smart investment, and over time will save you more than its value with its burning efficiency. In other words, the value of your saved buds, flowers and herbs will likely be greater than the value spent on the actual vaporizer. Especially when you crunch the numbers down the road. More on that subject is explained in detail in my Firefly 2 Efficiency article.

Firefly 2 Smartphone App

In my opinion, the most exciting upgrade to the Firefly 2 is the addition of the mobile app; where you can set the temperature, and easily switch between dry herb or concentrate modes. You can also select between a few heat levels for herbs, with only one heat level for the concentrate mode. Concentrate mode is the strongest heat, and should not be used with herb as it may cause them to combust and burn away. The app allows control on other device settings for a truly customizable and user-friendly experience. The FireFly 2 is Bluetooth connected and the app is available for iOS and Android smartphones/tablets.

Firefly 2 Smartphone Update

As of November 2016, Firefly updated the smartphone app with a “Boost” feature that allows fine tuning of the heating algorithm. Essentially, this makes the heating profile more customizable, and allows users to increase the vapor production or just turn up the heat. Using this new feature adds another layer of control and made a stark difference in overall performance. With the Firefly 2 smartphone app, you are truly in control of every aspect of your device.

Does TheVape.Guide recommend the Firefly 2?

The Firefly 2 is widely regarded as the vaporizer with superior flavor and the fastest heat up time in the industry. It is the best vaporizer for those who do not want to use too much material per session or those who wish to conserve their materials. Most dry herb vaporizers are “session” Vapes, meaning that 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. This gives it the efficiency and flexibility that so many vaporizer aficionados seek. 

Is the Firefly 2 worth the price?

The Firefly2 is worth the price. In my opinion, the Firefly 2 is one of the best portable vaporizers available on the market today (view full list here). If you are serious about vaping, the Firefly 2 is a necessary tool in your arsenal. It quickly became my favorite vaporizer, and if judging by the original Firefly’s life expectancy, it should perform well for years to come. Sure, you COULD buy a less expensive vape that will last you around a year, but the FireFly 2 is timeless and will pay for its return on investment in terms of material efficiency in very little time.

All things considered, the Firefly 2 is one of the best handheld vaporizers that I have ever tried and reviewed. It fits snugly in the hand, has a very long battery life, comes with two batteries, has a revolutionary glass makeup and pathway. It is lighter and made from aluminum alloy, and is one of the first portable vaporizers of its kind to offer one-hit-at-a-time in order to maximize efficiency and waste less material. If I were purchasing a handheld vaporizer, this would be a major player in my decision factor. The Firefly 2 is head-and-shoulders above the competition, and I would recommend this product for everyone and anyone who enjoys or is interested in vaporizing. If you are looking for a Firefly 2 vaporizer for sale, purchase directly from Firefly for a full manufacturer’s warranty and the best price.

  1. […] came across many blogs and reviews that claim that the Firefly 2is super efficient. Even in my own Firefly 2 review, I touched the subject of the Firefly 2 efficiency. But, what does that mean?  What makes a […]

  2. There was Fire

    There was the Pipe,

    There was the Joint

    The Bong

    and then there was the FireFly 2.

  3. 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.

  5. 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

  7. Great info. Lucky me I found your website by accident (stumbleupon).

  8. 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.

  9. I recently need three more puzzles done in order to complete the game, but am
    utterly caught at this time on all games.

  10. 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…….
