My iStick 30w stopped working yesterday.
I've had it since late January, so it lasted a little over 4 months.
I had it in my pocket with a Lemo Drop while I was doing some yard work. It worked fine while I was in the yard, but it stopped firing just as I was going back into the house. Black screen, totally unresponsive. The battery was fairly fresh - maybe a tick missing from the battery display.
Plugged it in and it seemed to start charging, although the screen at first had an unusual random flicker that went away after a couple of minutes. Can't vape while plugged in. Can turn the device on and off while plugged in, but as soon as the plug is pulled the screen goes blank.
Just ordered a replacement from Rocky Mountain Vapor, along with a couple of silly-cone cases. Lucky my 20w - which I've had since early October, 2014 - is still going strong or I'd be going nuts right now. (Good thing I subscribe to the "always have a backup" theory.)
Guess I'll pull the 30w apart when I have some time. At first I thought the battery might have come disconnected, but now I'm not so sure. If it did, I would think it wouldn't show the "charging" animation on the screen -- I would think, anyways.
Anyone tried the Kanger Subox 50? Looks interesting.
