Always keep a spare!
Review by Maxon 1/1/11
The battery works great and can last for up to an hour of constant vaping, but let me warn you all to keep a spare battery on hand at all times. So far I've lost a battery, had a battery malfunction, and dropped a battery which ended up broken. The malfuntioning one started working properly again by the way, but still I was stuck for some time using a battery that didn't work properly. Don't forget that unlike cigarettes you can't just drive to the nearest gas station to get your fix with these. These batteries are great quality, sleek, sturdy, and fairly priced, but always keep a spare battery AND atomizer in the case that you accidentally lose it or break it, otherwise you'll be so sorry.
