Query: waste of money

I had one before and had no problems so I upgraded to a 2GB. Radio freezes and no sound will come out. Power on can freeze and you have no way of turning device on and have to wait util it decided it is the right time.Item freezes up too much and then not only does Amazon and the Factory Depot give you the run around for a refund but they want you to get confirmation form sansdisk something is wrong with the item. So a refund isnext to impossible. Most of the items going out now form Sans for the Express are refurbished items!! Buy your electronics at a store!!!
