I thought I would let you know how tough your MP3 players are. I had a accident on my tractor driving through a field on my property. My Sandisk 8gb MP3 player was thrown in the grass and I could not find it for several weeks. I finally found it and it had been run over since I lost it, rained on and had quite bit of mud all over it.
I brought it back to the house recharged it and the thing still worked. Beside some heavy scratches on the display I am extremely pleased with its performance and would recommend your product to anyone.
