Bought this product as a gift and the first one didnt work - the lights wouldnt come on indicating charging. Completed my first Amazon return, and had a new one (that worked great!) before I could even get the broken one to the UPS store. Completely happy with the entire purchase (even the broken one because life happens and it was so simple to get corrected!)
