I love this light. Tiny, super bright, and durable. I just found mine in the dryer after I accidentally put it through the wash, and it's still working fine.
Edit: I've had it come on in my pocket a lot of times and kill the battery, which is kind of annoying. I also apparently smushed it too hard in my pocket recently and broke the power button. It just keeps turning on and off :( I still like it, but not as much as I used to. I'm waiting on some tiny star bits to open it up and see if I can fix the power button so I can actually use it again.
