Firefly 2+ Review

The Good: Excellent vapor quality | Provides a full spectrum vaping experience | Good battery life with fast recharge time | Works well with Wax in addition to Herb

The Bad: Choosing preselected temperatures using only the vaporizer is overly complicated | No temperature indicator on the device

The Bottom Line: There were only a few things I didn’t like about the original Firefly 2 so I was really happy to see that the 2+ fixed all of them. I especially like the improved draw resistance since now I can more easily inhale the great vapor it produces. The improved app that provides greater customization is also great. The Firefly 2 is the original on-demand vaporizer and now it’s better than ever.

Firefly 2+ and Firefly 2 Comparison
The big external difference between the Firefly 2 (L) and the Firefly 2+ (R) is the big light featuring the new logo that is located under the herb chamber.

In case you forgot, the Firefly 2 is one of those rare on-demand dry herb vaporizers. That means it heats up near instantly so that you don’t have to vape a whole bowl in one go. You can vape as little, or as much as you want, and come back to vape the rest when you’re ready. The Firefly 2+, in case you can’t tell, is an upgrade to the Firefly 2. So why 2+ instead of 3?

The reason is that the 2+ is an upgrade rather than a brand new model with brand new functionality. Those upgrades are pretty big though, and they make an already great dry herb vaporizer even better. So what are the upgrades and how is the Firefly 2+ different from the Firefly 2? Keep reading.

Differences Between the Firefly 2+ and the Firefly 2

Price: This is the one a lot of you will care about because the new 2+ actually costs less than the original. $80 less in fact.

Battery Life: The battery of the original Firefly 2 wasn’t bad, but the 2+ boasts an improvement in its duration.

Less Restrictive Draw: Perhaps the biggest drawback (pun intended) of the original Firefly 2 was it’s tight draw resistance. Well, now all of you who had complaints about that can literally breathe easier. The draw resistance of the 2+ is much improved (by 30% according to Firefly), which makes it easier than ever to enjoy the vapor it produces.

New Logo: As well as a new window to highlight that logo. The light is located underneath the viewing portal and lights up when the power is turned on. It’s not the most significant change but it looks cool.

Kit and Accessories

Firefly 2+ Kit
The kit of the Firefly 2+ consists of the following, L-R: Instruction manual, cleaning wipe, charging dock, Firefly 2+, concentrate pad, USB 3.0 cable.
  • Firefly 2+ Vaporizer
  • Rechargeable battery
  • Charging dock
  • Concentrate pads
  • Cleaning kit
  • USB 3.0 cable

Compatibility: The Firefly 2+ is compatible with dry herb and wax concentrates.

Optional Accessories

If you want to use the Firefly 2+ to its full potential, then you’ll need a good herb grinder. That’s because well ground herb gets heated more evenly and produces a better vaping experience. The SLX is available from Amazon and is one of the best manual grinders out there because of its smooth grinding action and its low maintenance.

Design and Features

Firefly 2+ Design
The touch sensors on the side of the Firefly 2+ must be held down lightly to initiate heating. The smartphone app allows you to customize which sensor should be held down.

General Design: The Firefly 2+ looks nearly identical to the original Firefly 2. The main difference is the window that highlights the new logo, which sits underneath the viewing portal. Aside from that new addition, everything else is the same, which is a good thing since the Firefly 2 was already pretty well designed.

The simple to use magnetic cover is still there, as are the touch sensors on either side of the device. The placement of those touch sensors does mean that you have to hold the vaporizer in a strange way that looks and feels unnatural. You don’t have to hold it that way for long since each draw is the equivalent of a full session in other vapes (more on that below). You can use the app so that you don’t have to hold down both sensors simultaneously, which does help alleviate some of the awkwardness a little.

As I mentioned previously, the viewing portal that allows you to see your weed being vaped is still there. So, whatever opinion you had of the original Firefly 2’s design won’t be changed with the arrival of the 2+.

Portability: The size and shape of the Firefly 2+ means that it is pretty easy to carry around. It’s a bit more pocket-friendly than most box style weed vapes since the rounded edges mean that it slips in and out of pockets easily. That’s good if you want to take advantage of the on-demand feature to take a quick hit or two on the go. If you’re worried about keeping the mouthpiece clean, you can easily remove it if you need to.

Build Quality: The body and magnetic lid of the 2+ are both made from magnesium alloy, while the viewing portal is made from quartz. The heating chamber is made of a ceramic superalloy that, along with the borosilicate glass airpath, ensures the purity of the vaped weed. The Firefly 2+ has the manufacturing quality you would expect from a vaporizer in the premium price range.

Smartphone App

The Firefly 2+ App allows to control settings such- selecting which button activates the vape, over-the-air firmware updates to the vaporizer, Setting up activation temperature, calibrate the vape for “richer” or “smoother” vapor, and many more.

Like most premium vapes, the Firefly 2+ has a smartphone app that gives users added functionality that is not available on the device itself. The main one is the temperature control. During each draw, the temperature goes from room temperature up to a fixed temperature setting. If you don’t have—or can’t use—your phone, then you can access seven different preset temperature settings using the device itself.

This procedure is rather complicated though since you need to press the left and right touch sensors in different patterns. Even if you somehow remember that process, there isn’t any way to know which of the presets you selected since there is no temperature indication on the device itself.

If you want an easier way to change the fixed setting, then you can use the smartphone app to do so. You can also use it to calibrate how rich you want the vapor or how smooth you want your draw to be. The app has links to instructional videos in the info section, just in case you need some visual aids to help you get started.

Finally, you can choose which of the touch sensors to use when you activate the heating of the device. The app has a clean, simple interface that is very easy to use. There’s a good chance that it will be one of the easiest to use apps on your phone. The app is available for both iOS and Android devices.

Cleaning and Maintenance

The Firefly 2+ is a pretty low maintenance device, but low maintenance doesn’t mean no maintenance, so here is what you need to do to keep it clean. For the heating chamber, you can use a small brush to clean out the bigger pieces of residue.

You can then use a cotton swab soaked in alcohol to wipe out the chamber and finish up the job. You can also use alcohol soaked wipes to clean the air path. As for the mouthpiece, you can use the pick that comes in the cleaning kit to cleanse it of any residue.

How to Use

Firefly 2+ How to Use
The magnetic lid makes loading the Firefly 2+ a very quick and simple process.

With Dry Herb

  1. Remove the lid, place your herb in the chamber, and then replace the lid.
  2. Gently press the touch sensors to start the heating process.
  3. Once the logo stops blinking and turns solid green, heating is complete.
  4. Inhale from the mouthpiece for seven to ten seconds.

As long as there is herb in the chamber, you can repeat steps 2 to 4 whenever you like.

With Concentrates

  1. Remove the lid and place a concentrate pad into the heating chamber.
  2. Dab some wax onto the pad and then replace the lid.
  3. Gently press both touch sensors to start the heating process.
  4. Once the logo stops blinking and turns solid green, heating is complete.
  5. Inhale from the mouthpiece for seven to ten seconds.

Temperature Range: 200°F – 500°F

What is Dynamic Convection?

Firefly 2+ Dynamic Convection
The dynamic convection heating of the Firefly 2+ allows all the terpenes in the marijuana to be vaporized during each draw.

One of the main features of the Firefly 2+ is its dynamic convection heating, what does that mean? Let’s take a deep dive to find out.

Convection Heating

This is the heating system where hot air is passed over the dry herb in order to heat it up.  This method heats the herb more evenly. And since the herb doesn’t come into contact with a heating element there is no chance that it can get burned.

While there are some good vaporizers that use conduction heating—which is when the heating element comes into contact with the herb—some vapers prefer convection heating because it better preserves the flavor of the dry herb.

Dynamic Temperature Range

During each draw, the Firefly 2+ goes through a range of temperatures, which is different from other vapes that are set at a fixed temperature for the duration of each session. Any time you inhale, the temperature starts out at room temperature, quickly heats up to 495°F, and then drops down to room temperature again.

Dynamic Convection

So, you put these two concepts together and you get a vaporizer that superheats your herb in a matter of seconds. So why is this important? Well, the various terpenes in marijuana get vaporized at different temperatures and the dynamic heating hits all of the temperatures at which the terpenes get vaporized.

That means vapes that heat up at a fixed temperature only vaporize some of the terpenes, whereas the Firefly 2+ vaporizes all of them in its temperature spectrum. This gives users a richer, more potent full spectrum vaping experience since they’ll be inhaling all of the terpenes and cannabinoids in their herb.

Performance and Vapor Quality

Firefly 2+ Performance
The dynamic convection heating of the Firefly 2+ provides users with a full spectrum vaping experience because it vaporizes all the terpenes and cannabinoids on each draw.

Vaporizer Performance: Since the Firefly 2+ is an on-demand vaporizer, it only takes three to five seconds to heat up depending on the preselected temperature. Since you generally use it for a quick session every now and then, you never have to worry about it getting uncomfortably hot. If you do decide to engage in back to back sessions, then you might find that it does get hot to the touch.

Dry Herb Vapor Quality: Thanks to the dynamic convection heating, the Firefly 2 has always had some of the best flavor from dry herb around, the problem was inhaling it because the draw resistance was so high. The 2+ fixes that problem by lowering the draw resistance, so it is now much easier to inhale all of that flavorful vapor.

Hits from the 2+ feel a little stronger than they do with other vaporizers since, as I mentioned before, the dynamic convection makes each hit feel like a complete mini-session. So, even if you’re a vaping vet, you might want to take it easy, that goes double if you’re a newbie. No matter your experience level, you don’t have to worry about the vapor getting hot, regardless of the temperature setting you choose. That is because the glass airpath helps to cool down the vapor before it hits the mouthpiece and your lips.

The 2+ doesn’t produce a lot of vapor since the majority of the weed gets vaporized and inhaled. As far as Firefly is concerned, a lot of vapor means a lot of wasted terpenes. So no big visible clouds from the Firefly, but still very potent hits.

Concentrate Vapor Quality: Concentrate performance is not as strong as the weed performance because the Firefly 2+ doesn’t reach the temperatures that wax concentrates need to reach maximum vaporization. Plus, you need to insert the concentrate pad anytime you want to vape some wax and then remove it when you’re done.

That can be pretty inconvenient compared to how quickly you can load a dedicated vape pen. Still, the concentrate performance isn’t bad, but it’s not why you would buy the Firefly 2+. I would stick to weed vaping when using the Firefly 2+ since that’s clearly where its strengths lie.

Also, I always recommend that you not use your main herbal vape for extracts. Using extracts i your herb vape makes cleaning and maintenance more difficult, plus you will be doing it more often. If you want to use extracts, then I would suggest buying a Wax Pen instead. It will do a much better job of vaping your extracts, plus you get to keep your herb vaporizer in top shape.

Battery Performance: The battery lasts for a decent amount of time. I was able to get an average of eight bowls before I needed a recharge, and I was able to get about eight draws per bowl. That makes for an average of sixty-four draws per charge, and you could probably squeeze out a few more if you set a lower temperature than I did. Recharges are quick, at just forty-five minutes. The battery is removable, but it needs to be in the vaporizer while it recharges, which lessens the convenience of a removable battery somewhat.

Firefly 2+ vs Ghost MV1

The MV1 is the only competitor to the Firefly because it’s the only other on-demand vape out there, which shows you just how rare they are. The MV1 has a lot in common with the Firefly 2+, such as the fact that is also a dual-use vape and it also has a smartphone app. However, it uses regular convection heating instead of dynamic convection, plus it’s a lot bigger and less portable, and it costs more than the 2+. If you want a more detailed look at their similarities and differences, then you can check out the Firefly 2 vs Ghost MV1 comparison.

Bottom line

The Firefly 2+ is exactly the upgrade the original Firefly 2 needed. It gets rid of all the weaknesses of the old version while retaining its strengths. So, the draw resistance is much lower, the battery life is improved, and the price is much lower. Meanwhile, the excellent vapor quality is still there. So, if you’ve never experienced an on-demand vaporizer before, then the Firefly 2+ is a great place to start.

Who is it for: Anyone who needs to vape RIGHT NOW! Vapers who want a full spectrum experience in a short amount of time. Advanced vapers looking for top notch convection vaping. 

Who is it NOT for: Users who want a lot of visible vapor from their vape. New users who are looking for a simple “point and shoot” vape.
