billherbst, I was thinking of buying the new ones from Vapor Beast but want to make sure it doesn't have the issues as stated in the link provided by hmlessalky, post # 581 in the official CCV information thread. Would you mind testing your unit as described and letting us know-Thanks. "...Thats cause you pushed power button 6 times not 5,,,if you push 5 turns off but if you push it again it goes into that low voltage mode just bug in chipset design,,,no big deal, trying to get all people purchased a v1.5 a version 2,,, the issue is very serious,,,tube left sitting on table just shorts out tube and carto so hot can't touch it smoke starts rolling out from inside the tube, mine did it yesterday, i immediately pulled them from site,,,, now most work great but few is to many in my book."
