Query: DO NOT BUY THIS PLAYER

My first RIO Forge 512 lasted only 4 months before the volume button stopped working. After calling RIO, they agreed to send me another. Now, after another 3 months, the same thing happened again. The problem seems to be that the buttons are extremely fragile and break after just casual use....yet this is supposed to be a "rugged" SPORTS model?! RIO claims that it is not a design problem, and wanted me to pay $89.00 to have it rebuilt. No wonder they only offer a 90 day warranty. Sorry, I cannot afford to keep replacing my MP3 player every 3 or 4 months. Do a routine search on the internet about customer satisfaction with this unit, and you will find countless complaints that are similar. The unit is a piece of junk and is definitely not ready for prime time. Save your money and buy something else.
