I've been eyeing this LED bracelet for a while and finally got it. Unfortunately, I may have not fully understood the item description when it said " These bracelets are “shock activated” and also have pulse motion sensors for extended use!". The light does not stay on at all. The shock-activated meant it lights up upon sensing movement, or when you tap it. Perfect for concerts or clubbing indeed, but I was thinking of using it at night when I walk home from work so passing cars can see me.

It is very bright and fits my wrist well. I just wish there was an option to keep the light on for some period of time.
