The Firefly 2 and the DaVinci IQ are two of the newest vaporizers on the market, and they offer an exciting range of features on paper. Between the two, there seems to be something here for everyone. The Firefly 2 is fully convection and designed to deliver unbeatable flavor, while DaVinci built the IQ as a testament to how good and versatile conduction heating can be. Marketing claims are one thing, performance is another. Today we’ll find out which one lives up to the hype and which one leaves quite a bit to be desired…

 


Vapor Quality

The Firefly 2 is capable of delivering some of the best tasting vapor I’ve ever experienced from a portable. I would say that it is on par with the Mighty, meaning there isn’t a vaporizer that can actually surpass it. To that end, the vapor is excellent.

There are some problems, though. First, getting a great draw isn’t always easy. You have to let it heat for a few seconds before beginning, then draw very slowly. This is fine, but the draw resistance is more restrictive than I prefer. I didn’t notice this as much at the beginning. My guess is that you need to keep this very clean if you want an acceptable draw resistance. Some other small gripes are the quick shutoff and frequent lack of any visible vapor at all after you exhale.

So while the flavor is great, the overall experience isn’t always that enjoyable. It feels more like work than most vaporizers.

DaVinci IQ

The DaVinci IQ has very good vapor as well. The flavor is actually surprisingly good considering this utilizes fully conduction heating. It’s not on the same level as the Firefly 2, but it’s still very enjoyable and preserves a lot of the individual characteristics of different varieties of herbs.

While the Firefly 2 has the advantage on flavor, the IQ delivers better vapor density and cloud size. I also find it easier to get good vapor from the IQ, though I did have to stop and stir the ground herbs more often than I did with the Firefly 2.

While most people would probably give this category to the Firefly 2, I don’t think it deserves it. When you factor in flavor, density, and overall enjoyment into the equation, these are evenly matched in overall vapor quality.

Build Quality

Firefly 2

Build quality is the area where I wish Firefly would have put more effort into. The idea behind it is good, and it definitely looks like a premium vaporizer, but the execution is lacking. There are just too many problems that have come up over the last year. At the very least, they are lacking on quality control. Some people seem to love their unit and have no problems, while others have a list a mile long.

My biggest complaint is the battery. Each battery only lasts for a few sessions, so they give you two in the box. The problem is that the more you use them, the less charge they hold. The charge indicator never seems to be right either. Even with two batteries, the overall battery life is still pretty low compared to what most vaporizers are capable of.

I also don’t think they took a good route regarding changing the temperature. You can’t actually adjust it at all from the device itself, you have to use the included app.

DaVinci IQ

I think the IQ is built much better. It has it’s problems, but they aren’t nearly as significant as with the Firefly 2. For the most part, the materials used and the actual build of the IQ are excellent.

The IQ really shines when it comes to adjusting the temperature. You can change it in one degree increments from the device itself, and it’s app is used to unlock special heating styles like smart paths and stealth modes. The smart paths are especially cool because they automatically increase the temperature throughout your session to help you fully extract everything from your herbs.

I’ve seen other people have problems with the battery they get with the IQ, but fixing this is cheaper and easier than it is with the Firefly 2 because the IQ uses regular 18650 batteries.

Portability

The Firefly 2 is small, making it very easy to carry around with you. The problem is you won’t be able to use it much before you need to recharge it.

If you only want to enjoy one or two sessions when you’re out, this would be fine. If you want something that could offer more, you’ll have to carry extra batteries with you or get something else.

DaVinci IQ

The IQ is also small, but it has a slightly better battery life. It will ultimately come down to how to use it, but I’d guess that you will get 1-3 extra sessions from the IQ off one battery with a full charge.

Again, you can get more by carrying an extra battery, but that decreases the convenience of carrying it slightly.

Discreetness

Firefly 2

The Firefly 2 is small, which is an obvious plus. But it has bigger strengths if you are trying to make sure you don’t attract unwanted attention.

First, the on-demand heating and fast heat up mean you can take sporadic draws without wasting your herb.

Instead of needing a full 5 to 10 minutes to enjoy a session, you can take advantage of any opportunity to take a single draw. The lack of visible vapor is actually a strength here as well.

The one downside is that it’s held like a pipe.

DaVinci IQ

Like I mentioned before, the IQ has a stealth mode built right into its heating styles. This mode will keep visible vapor and odor to a minimum by heating your herbs less.

The overall size of the IQ also makes it easy to keep concealed. While it is also very discreet, I’d say the Firefly 2 has a slight advantage here.

DaVinci IQ Portable Showdown Winner Winner: DaVinci IQ

The DaVinci IQ is our winner!

I just don’t see why people love the Firefly 2 so much. The flavor may be great, but using it is much less enjoyable than using other vaporizers. And even if the flavor is excellent, it isn’t anything that we haven’t seen before from other fully convection portables like the Mighty.

The IQ offers a much better overall experience. The vapor quality is still fantastic, and even beats the Firefly 2 when it comes to vapor density. The build quality seems to be significantly better, especially when it comes to adjusting the temperature. I think vaporizers should be fully functional without apps. If they have an app, it should be to enhance the experience. DaVinci did this well with the IQ.

If you are thinking of picking up a Firefly 2 or the DaVinci IQ, we recommend grabbing them from TVape.com, they have no tax and free shipping on orders over $100.
