Firefly 2 Vaporizer Review

Firefly 2 in hand
The Firefly 2 is a phenomenal, pricey vaporizer for dried blends and concentrates.


Unless you’ve been living under a rock for the past few years, you’ve almost certainly heard about the Firefly. It’s always featured on “best of” lists in all of the top publications. It’s received high marks from some of the best and most widely read vaping blogs. Your buddy who owns one hasn’t shut up about the Firefly since he bought one, and whenever you bust out another vape at a party he always has to talk shit about it and remind you why his Firefly is even better.

So now you landed on this review because you’re wondering if the new Firefly 2 is really able to live up to all the hype, and moreover, you’re wondering if the $329 price is justified given the fact that you can buy tons of vapes for sub-$100.

The short answer is: YES.

The Firefly 2 definitely met my already inflated expectations, and I think it’s more than worth the high price.

Here’s why.

Appearance and Design

The Firefly 2 maintains a similar appearance to the wildly popular original Firefly, but 55% lighter and 33% smaller.

The first thing you see when you open open the box.

The team at Firefly Vapor managed to achieve this feat by switching out the material used to make the body. The original Firefly body was constructed out of aluminum, while this new and improved version is built out of a die-cast magnesium alloy. Aside from making it lighter than the original version, this new magnesium alloy construction allows for a much thinner construction and a significantly lower thermal transfer rate, which does wonders for keeping the heat contained within the device.

The underside of the faceplate and the top of the chassis are both lined with a layer of Gorilla Glass. This created a nice, easy to clean glass airpath and shows the attention to detail that the design team put into the Firefly 2.

It’s obvious that the design team from Firefly Vapor put a lot of effort into making this vaporizer look as sleek and minimalist as possible. The minimalism design aesthetic is definitely trending in the vaping industry, as it is in the tech industry as a whole thanks to the influence of a certain company named after a delicious fruit. But rather than being a clone of other Apple-inspired technology, the Firefly manages to add it’s own unique take on that minimalist design philosophy.

Basically that was my long-winded attempt at saying that the Firely looks both stunning and expensive. You’ll definitely be proud to pass around the Firefly next time you’re vaping with your friends.

Ease of Use

The way you activate the Firefly 2 is really cool, high-tech, and unlike anything I’ve seen in any other vaporizer (and I’ve used plenty of them). To fire it up, all you need to do is place your fingers (thumb and index finger) on both sides of the unit and it’s ready to go. Your first instinct will be to press down on the sides of the devices to activate it, but I can assure you that this is completely unnecessary! The Firefly 2 has super-cool capacitive sensing technology that detects when you put your fingers on the devices and it automatically activates.

The orange glow while heating is a VERY cool feature.

After five seconds you’ll see the chamber glow orange through the glass viewing port. The gorgeous and calming orange color also glows through the grooves on either side of the unit. I thought this color change was extremely cool and helped to build anticipation for the hit that was about to come. It also added to the high-tech feel of the Firefly 2, making me feel like I had a really finely crafted piece of vaping technology in my hands. While I have used other vaporizers that incorporate a light that lights up when the unit is activated, none of them look as cool as this one.

When you buy your Firefly 2 you’ll also get access to a smartphone app (available for iOS and Android) that allows you to control the temperature settings. The app is easy to use and switching the temp settings on your phone works seamlessly with your connected Firefly 2. I didn’t notice any significant lag time.

So at this point I was already won over by the Firefly before I even took a hit off of the device. How did the performance stack up?


The Firefly 2 features six different heat settings: five for dry herbs and one for concentrates.

The Firefly 2 is a stunning, high performance vaporizer.

It can reach a heat of 400 degrees Fahrenheit in a lightning fast three seconds, and reaches 420 degrees in five. The borosilicate glass bowl, combined with the aforementioned magnesium alloy body, does an excellent job of containing the heat. Even when putting my finger directly on the glass and holding down the sides to activate it, it takes quite a long time before I start to feel any of the heat on my finger.

The bottom of this really cool heating chamber is made out of a metal plate that features 55 precision, laser-drilled airholes. This is one of the major differences between the second generation Firefly and the Firefly 1. The first generation Firefly contained only six holes that were larger in size. The company claims that by spreading out the heat over a large amount of tiny holes, the Firefly 2 can be run at much higher temperatures while still maintaining excellent performance. I haven’t personally vaped with the original Firefly, but I can attest to the fact that the airflow on the Firefly 2 is phenomenal.

The heating coil is not made out of nichrome, as with most other vaporizers. Instead the creators behind this device spent over four months researching and testing different materials before settling on an undisclosed material that is designed to prevent some of the problems that come with using nichrome coils for extended lengths of time.

The new upgraded batteries feature a battery life that is twice as long as the batteries of the original Firefly. The package includes two batteries, so if the first one dies you’ll easily be able to swap it out and keep your vape session going. It also includes a cool USB docking-station type of charger.

Overall, the Firefly 2 is easily one the best portable herb/concentrate vaporizers that I’ve ever used. It may be a bit pricey but if you can afford it the Firefly 2 is definitely worth the money. If you can’t afford it, save up until you can. It’s that good.
