Originally it was only usable with flower(though I’ve run kiefed bowls through it and it handles those fine.) But when they released the FF2, they put out concentrate pads for that, and the chamber sizes are about the same, so you can order concentrate pads for the 2 for use with the 1.

The batteries for the 2 are also reverse compatible, so you don’t have to worry about not being able to find batteries if you live in a city with headshops, and you can order them online from Firefly if you don’t.

People have also found that the bowl screens made for the Arizer Solo fit into it perfectly. This takes away the need for the screen on the bottom, allowing for a more free flow of steam/hot air. It also has a secondary effect of suspending your herb slightly above the holes the hot air is coming from, making its convection qualities even better.

There are a lot of great hacks like that available in the 275+ page Firefly thread at fuckcombustion.com.

Basically, if you’re like me, and you love the Magic Flight Launch Box, this feels like the Launch Box 10.0. Very similar in function. Miles apart in vapor quality.
