PAX 3 vs. Firefly 2

Firefly 2 vs PAX 3

Comparison Breakdown

The PAX 3 and the Firefly 2 are verrry different vaporizers.

Both of them are portable, and they’re both very good, but the way they heat and the way you use them varies a lot.

The Firefly vaporizes your material with super-heated air (convection), and the PAX heats your product with radiant from the hot oven walls (conduction).

They both have their advantages and disadvantages and honestly, everybody should make room in their collection for one of these (or both).

  • Welp no comment on pax3. I love it. Use the oven lid to compact the herb before you power it up. You can put a bit under the mouth piece to decarb and get it full of resin.

    You can buy premium helium balloon to connect it to a bong. The part you owe into goes over your bong where the bowl would go. Then cut dat der balloon’s bulb part in half and jam it on the pax. Puff on it as you would without the bong.

  • I just received the Firefly 2 yesterday and I love, love this vaporizer, I’m 65 years old and I been smoking for longer than most of you have probably been alive, so I do speak from experience. I had no problem with the learning curb that I have read about due to the fact that I watched the video’s and read how people who own this amazing vaporizer use it. I was vaping with amazing clouds as soon as the battery was charged. I sip my herb I seldom do a whole bowl at one time. I like to take a hit or two and continue on my way and this is suburb for that. I have wasted so much herb by sipping like I do but it is the way I enjoy it. I was so exited to see a vaporizer that allowed me to do this with no waste. I expect I will recoup the expense of this unit in no time. When I first received and set this up last night I vaped two bowls because it tasted so good, If you are thinking about buying this vaporizer don’t wait another second. The cost is a little steep but you really do get what you pay for. I have wasted so much money trying to save my lungs with different vaporizers Just to be disappointed. I am so glad that I took one more chance because Firefly 2 is the one I hope to use for another 20 years of sipping.
    P.S. While you are waiting for your Firefly 2 to be delivered start reading and watching the video’s that are out there. This way you will be ready as soon as the battery charges.

    • Love the firefly 2. I’m 60 and I know after years of cigarettes, my lungs def need a break. It does have pluses and minuses, but overall I agree, it is the BEST. The convection heating vapes with a less harsh effect on the lungs. You can taste the real taste of the herb. Bought mine off of Ebay, no issues. Stripped mine down and cleaned from the board up. Even have it “geeked out” with a star Trek decal and small silicone feet – can’t be scratchin’ my bud.
      I was just looking at the pax 3 line, but it is convection heating. I did see an article about the firefly 3 – possible larger bowl and more precise temp control. What it needs is heptic feedback (vibrate) and some cooler LEDS – lol

    • It is “learning curve” not “learning curb” But the errant descriptor evokes an apt descriptor as most curbs hinder movement. Learning requires patience, effort and a brain.

      • Simple mistake, give some slack as I’m sure you have been in those shoes before, you’re not perfect. Of course unless you’re a robot, in that case go screw yourself.


  • i owned a FF2 had to return it 2 times for battery fail had to reset all the time
    and burnd my herbs realy hard on medium high and 104 tuning
    love and hate situations
