Q: Great American classic that you can get for free on kindle. I was supposed to read this back in high school but wasn't not interested at the time. But now with the benefit of age I can really appreciate it.

A: Positive
****
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: At 60 pages,this is over-priced and not a course for adults. As basic instruction for those 10 and under, it is probably okay. For anyone who even doodles while talking on the phone- forget it!

A:
Negative
