Query: Waste of money

Pros: NoneCons: I bought six of these to give as presents, only two of them were still working at all after 30 days and one of them has a sticky tray. The phone number you have to call to get an authorization for warranty service goes unanswered permanently and there is no other way to proceed. This is a junk product from a junkier company, I will never buy another product from this manufacturer.
