i've bought 5 players over a period of 3 or 4 months from Uxcell for myself and a few friends. They have never let me down once. All the players arrived within 12 days of the shipping notice.
You shouldn't have to format the player when it arrives because Uxcell definitely do not sell hacked players. If you buy a 4GB MP4 player, thats what you'll get.
You can format it if you want, just to give a fresh file system to start copying files to.
