[EX Q]: 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.
[EX A]: Negative

[EX Q]: The subject is trivial and boring. The writing skill mediocre.I was stuck in Sri Lanka and downloaded it by mistake when learning how to use my new kindle. Decided to take a look.Sorry, perhaps just not my type of book. It is no literature.
[EX A]: Negative

[EX Q]: This is one for the hard core action fans. There's very little 'down time' to run for popcorn. If someone isn't getting shot, punched, etc. things are getting blown up or sunk in water. There is an action scene I haven't seen yet with a police car. Several of the action scenes are worth a rewind and I did appreciate the 'buff bodies'. You have to give these guys an A plus for working out.Chrissy K. McVay - Author
