I had hoped for a more from Sandisk. After about 10 very frustrating days of trying to get it to work properly, the unit stopped altogether. The expansion memory never did work. It would only duplicate what was on the internal memory. Sandisk support was polite and tried to be helpful. Unfortunately, we were not in any way successful in getting the unit to work. After I got the error message on my computer that the unit has malfunctioned and should be replaced, I sent it back.SanDisk Sansa View 8 GB Video MP3 Player (Black)
