The PAX 3 vs. The Firefly 2

Firefly 2 vs PAX 3 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 advanatges and disadvantages and honestly everybody should make room in their collection for one of these (or both).

Check out the table below for the main differentiators:
