BEWARE: The product works as it should, but when you try to get your rebate through Paypal, someone has already used it. They don't tell you that up front. They're either used or more likely, they buy them for retail and use the number to get their money back with the rebate from Paypal and then sell the readers for a discount on Amazon. Nice racket if you can get it. If you want to get a 'free' reader, you need to get one from Paypal or from a retail store.
