I've got a genie. It's a good butane powered model because of the ceramic filter. The filter helps keep the herb from burning, but it's still tricky to get vapor and not smoke (you'll know the difference pretty quick ). I highly recommend a torch lighter with any butane powered vape. The flame is hotter so you can hold it farther away from the unit and it doesn't produce soot like a regular lighter. It's also a steady flame for better heat control. You do need to get one that you can 'lock on'-plenty of affordable ones on ebay.
