Man... I got my first semovar v1 and kayfun and I'm floored by how awesome this thing is! Sad I missed out on the v3.1... Anybody buy an extra they want to sell me

These things are out performing all of my other devices by leaps and bounds! Even my beloved hell fires...
However that being said, I do get the occasional dry hit, and I know I'm not suppose to. It would be great if one of you svoe pros would post a kayfun tutorial in English. That would help a ton!
Either way, they are the best I've tried to date, and I've pretty much owned/own most rbas.
