Input: Consider Input: Despite the many reviews from folks who had to return one or more Sansa Views before getting a functional one, I figured the manufacturer must have cleared up their quality problems to stay in the market. Wrong!!!!My brand new Sansa View 8 totally stopped functioning about 20 minutes into its first use. I'm very disappointed to have waited for my order to be filled and now must wait again for a replacement. I'm more than a month into my purchase and I have nothing to show for it but a paid bill.Amazon has not stepped up at all, either. The order was filled by a vendor whom I've never heard of before. Amazon refers buyers to that vendor's customer service and takes no part in satisfying the purchaser.Lots of room for improvement on the part of all three providers.

Output: Negative
