I'm taking it on my pilgrimage to Spain in a few months. I do not like the fact that its so easy to accidently switch it on when its in you pocket. Almost every day its in my pocket, I see through my pants that it has switched on. Wish it didn't switch on so easy.

The only issue I have is that it is too easy to inadvertently turn it on while in your pocket. The cover that lays over the power button actually will turn on the light if pressed. The cover is a large portion of surface area so turning the light on by accident is all too easy.

I gave this to my wife and she couldn't be happier with it. It's really light and works quite well on a keychain, unlike other so-called keychain lights which she has tried and which were much heavier. Great styling, too. Now I need to get one for myself.
