[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]: "Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.
[EX A]: Positive

[EX Q]: We had to buy a new lunchbox for our son after 2 months (a different brand, machine-washable) because this one is way too hard to clean. I have turned it completely inside out, scrubbed between all the cracks, and still food is stuck in the seams andthreads. It is very durable, but we can't get rid of the smell or stains with a reasonable amount of effort.
[EX A]:
Negative
