Q: This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.

A: Negative

Q: All the elements of a great movie. What can I say, I love to study the elements of war, and I enjoy a good love story along the way. This movie was a great introduction to the role airplanes had in the first World War. Featuring the story of the Lafayette Escadrille, and the role Americans had in the early aerial engagements. The story also allows those who have little knowledge about early technology to understand that it was very rudimentary. (Using hammers to clear your machine gun comes to mind.) The soundtrack was very well done, and the needed animation(?) was excellent as well. I highly recommend this movie.

A: Positive

Q: I've had HP printers for years and have always liked them. However, this printer is a real headache. We've had 3 --taking the time for returns was a hassle. With each of these HP printers, the paper feed mechanism has been defective. With every document I printed, the feeder malfunctioned and the paper was torn or badly misaligned. I found out on the HP website that others have had similar problems with a number of HP printers--malfunctioning paper feeds. HP has done nothing to correct this problem. I've now become a Canon printer owner am quite happy with Canon printers--excellent quality and no problems. I'll never buy another HP printer.

Negative
