Query: Update on Rio Nitrus Garbage

Okay, this is my second post. I upgraded the firmware on both faulty players (2 out of 4 purchased didn't work). One had no change and is completely worthless (powers off in 5 minutes or less) the other worked great - for one whole day. Now both are completely worthless and in the garbage. Money down the drain. The other two? Working flawlessly. That is 50% failure. Flip a coin. Maybe you'll get lucky. Look at the reviews here. Everything is either 5 stars or 1. That is very scary. Buy an Ipod, I guess...
