ok got 2 of these yesterday. used it for a couple of hours last night and pretty much all morning today. Mine only crackled and popped for the first few times then went into smooth mode. so far i am extremely impressed with its performance. Flavor and TH are fantastic and the vapor even exceeds as it appears to me the LR306. as others have stated it does go thru alot of juice. i guess the only question will be longevity. if i can get a good 4-6 months out of this its definately worth the price. going to use it for a bit and then make a video on it. in conclusion for now its #winning!
