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!

Ex Output:
Negative

I wish I hadn't spent the money . . .It follows in the same style as the other two Transformers movies, but it turns the formula up a bit. There's more action and more bickering between characters, but plot, story and character development, drama, and any semblance of intelligence are sacrificed for it.Yes, the special effects are cool, but the dialog and interaction between characters is downright painful, which kept suspension of disbelief from kicking in.If I had it to do over again, I'd rent this one.
