Owners of the new sleek iPod Nano are complaining that it breaks too easily.
They say that the screens of the tiny 9cm machines are breaking and getting scratched - and sometimes they've just stopped working.
A special website has been set up to collect emails from angry owners of the mini iPod, which was launched earlier this month.
Manufacturer Apple hasn't made an announcement about the complaints yet but say it has been thoroughly tested.
The Nano is the thickness of five credit cards, can store 1,000 songs and costs about £180.
Matthew Peterson set up the website and says he's getting about 30 complaining e-mails an hour.
He said: "My Nano broke on day four. The screen that is. It shattered. It was in my pocket as I was walking and I sat down. No, I didn't sit on it, it was just in my pocket."
