I bought a kindle for my husband at christmas time this past year. After having the kindle for about 7 months and using it almost daily, one day it froze up and we tried everything, called help desk for suggestions but to no avail could we get it to work. Amazon sent us a replacement kindle within days and send a return label for me to send back the old one. No cost,,,,I said NO Cost!!! Amazing!! My husband is now back reading his kindle and enjoying it more and more. Thank you Amazon and Kindle for standing behind your product!!! My daughter bought one after she seen my husbands and she also loves hers. Amazing for someone who loves to read !!!!! Thank you again to Amazon and Kindle for all your help !!! Very Very Satisfied Customer!!!!

Amazon rocks !!
