this review title is: works but watch out for the little screen and the content is: i have bought two of these since they work well unfortunately though both times i have 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 would think the company would provide extra screens since they are so easy to lose.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
