welllllll my chana died!!!! I got 3 good months out of the cloupor version. I was in my car and smelled something burning looked over at my hana and it was smoking a ....*. I had taken a hit maybe a minute before put it down and it started smoking. I took the battery out and waited a few and put it back in and bam same thing. Got home took it apart and the chip is fried big black burnt spot in the middle of the chip. It could have been charging in the cig lighter i dont rem but im kinda ...... cuz i just got the mini nautilus and now i cant use it all I have is mechs(alota mechs). Guess i have to wait for my Sigelie 100 watt but who knows how long that shenanigan is gonna take
