Reviewed by Sam. E - 10th Sep, 2020 Bright.... But not for long A great idea for finding keys etc in the dark, say in an emergency or to not wake others up. And it really does glow. But only for a couple of hours. Left it in the sun all day then put it with my key in the door... By time it was dark out an hour or two later it barely shine at all. I'd be better off sticking one of those pound shop glow in the dark stars to my keys. Otherwise good size.
