I'm on my 3rd Kindle, and DH is on his 2nd. They don't quibble - they just send a new one. Pactically overnight. My only problem is with books that haveto be downloaded via UBS to computer. Half the time I can't find them on my computer. Amazon has tried to help, but when you're working with someone via the written word vs on the phone, it's very frustrating! However, that's my ONLY problem. I LOVE my Kindle!
