Query: Terrible product - do not buy!

I gave a very positive review to this player last year. Unfortunately, there's a follow up on January 30th, 2008: I need to modify my original rating. The player suddenly stopped working last week - I last used it about a month back - now it appears to be dead. I've tried to charge it using the usb port on my computer : the player starts to charge, with the backlight alternately but irregularly coming on and off, and will start to boot, but then shuts down, starts to charge, with the backlight turning on and off, then starts to boot again but shuts down(before it gets past the Vibez screen) etc etc. Contacted customer support - they were of no use. I now possess a beautiful paperweight! Buy this player at your own risk.
