Review title is Works, but watch out for the little screen [SEP] I've bought two of these since they work well.  Unfortunately though, both times I've lost the little screen, which ends up making the device mostly useless.  The screen is a pain to clean, and very easy to lose.  I guess, for the price, this is about as good as it gets.  However, I'd think the company would provide extra screens, since they're so easy to lose.
