Bests & Worsts Reviews from Amazon

I literally just got this and it already stopped working. I read the reviews about this happening but thought maybe they were just unlucky. I unboxed, charged the battery to full, and tested it for 10 minutes. It worked great! I then tried to actually use it the next day. When I pressed the button, there was a *click* and nothing happened. Maybe fuse shorted? Battery is still green but the device doesn't turn on at all. Disappointing for so much $. Returning this one.
