CCELL M3 Battery

The no-button design is so sleek and the inhale activation works perfectly every time. This little stainless steel battery fits my pocket easily and charges quickly with the 510 thread USB.

The inhale activation works flawlessly, and the stainless steel body feels much more durable than my old plastic pens. My only small gripe is that the 350mAh battery drains a bit faster than I'd like with heavy use throughout the day.

I was pleasantly surprised how sturdy the stainless steel housing feels for something so small. The inhale activation works instantly and the battery lasts me through a full day of casual use, though it could charge a bit faster.
