This product works as advertised. It was purchased to charge a Motorola Razr phone which it will not do. This is consistent with many other products which do not work with this phone. Not the chargers issue. Motorola makes crappy products. Will add this to my stock of mini usb chargers to use on all the other MP3's, GPS's and phones for which it does work. Will give the Razr the parking lot stomp soon.
