I don't like to write bad reviews but I do always want to be honest and honestly this item is a bit of a let down.  I can't really complain as it was just under $3.00 but it isn't quality by any means.  The light itself is not very bright and the button to turn it on is right under the end of the clip.  This may be a common place to put the on button but here the clip is pretty tight so it seems to turn itself on even with the slightest unwanted pressure.  As far a pressing the on button it is very small so you have to make sure you press down just in the right spot or you'll be fiddling with it for sure.
