I recently purchased my Sandisk 8gb mp3 player and the wheel is sticking to the point I have to pull it away for the recessed grove to increase the volume. I have issue with having to pry the wheel off to get it to move.
I purchased it thru Dell Computer and good luck trying to get a straight answer or an operator that will give you a phone number to try and get this problem corrected.
I was hung up on once, I had a difficult time understanding the four people I talked to and was given wrong information three times. That is why I am trying this route.
