[Q]: I was very excited to buy this scanner and was pleased with its size and weight. However, if you have a Vista operating system, like I do, IT WILL NOT WORK! The company told me that they stopped selling this product over a year ago and there are no driver updates available for this product. If you have an older computer and an older operating system this product might work for you. But as for me it was a waste of money!
[A]: Negative


[Q]: This thing is awful. Prints magenta only. Drives me crazy. I am going to go find a high building to throw it from.
[A]: Negative


[Q]: I ordered this book 2 weeks ago and it just now came today. What's worse, it's in absolutely terrible shape. The front cover is ripped, the spine has old sticker residue on it, and the back looks like it's been chewed on by a small animal. So much for being "Used- Very Good Condition"
[A]:
Negative
