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: I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

A: Negative

Q: Hi i got this game by trading my brother for some stuff he wanted and i started playing it and was disipointed cause you have to shake it so much. But luckily i figured out how you can get in battles and stuff without having to shake it at all. But it depends on if you you have a massage chair or not because if you have one you can set your magaman pet on it and it shakes it!!! I was so glad when i figured out how to get in battles without shaking it because my arm was hurting now i find the game real fun. I hope this review helped you see yah.
