Great idea. Always with me on a key set, Quite enough power to find my way in dark alley.
Minus two stars because it turned on three times in my pocket this week and every time I found it because it got hot.
A little bit more and my bolls would get turn well done.
It also turned on when I decided to drop keys with the torch to my backpack to keep my bolls intact. .
So. great mini torch, but ON/OFF button location is highly questionable.
