The Firefly 2 is a marvelous improvement upon the original. At 140 grams, it’s half the weight. Measuring a compact 5″ x 1.6″ x 0.8″, it’s one-third smaller than the first generation. It’s easy to hold — comfortable. The materials and construction feels solid and it looks quite dapper, with the heating chamber visible through a glass porthole in the magnetic face plate.

To fire it up, just hold the Firefly with your thumb and one opposing finger touching — not pushing — contact points on either side of the unit. It took me a few days to stop wanting to push the buttons in; really you just touch them and the Firefly turns on

To vape hash oil, press one of the included stainless steel concentrate pads into the chamber and dab a little oil on it. Give it 5-10 quick puffs to get it going, then draw like normal.

Aside from how difficult it is to pack while standing, there aren’t many shortcomings to the Firefly 2.

Pros:

Amazing flavor. I can taste flowers for the first time ever…. I wasn’t able to before because my taste buds aren’t very sensitive.

Almost no smell

Durable, I dropped it on the hard floor several times and it only has the tiniest scratch

Easy to Clean

Cons:

Gets hot, sometimes painfully hot. Sometimes so hot battery stops working and I have to switch batteries

The buttons to activate the vape don’t always respond. Once every 50 times it won’t detect your fingers

You have to take long slow hits to make it work well
