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: While Jawbone make a great blue tooth ear bud, it doesn't interface with ears well. The Jabra solution doesn't work. It doesn't hold the ear bud well allowing it to fall off at the most inconvieniant times. It also hurts your ear and is difficult to insert. It's not the answer, friends.

A: Negative

Q: Product was defective from day on and lasted a whole 32 days and now will inflate but by the middle of the night you sleeping on the carpet.
