[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]: By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!
[A]: Negative

[Q]: This by far the worst movie that I have ever paid to see at a theatre. That is not to say that it wouldn't make a good rental; where through multiple viewers you could knock the viewing price down to 15 cents a person, but then that would still be too much to pay for this movie. WWE Entertainment should stick to what it does best - wrestling events where the story line is better inside the squared circle. Outside of a Terminator reference made to Robert Patrick, this is a total waste of 91 minutes of your life.

Negative
