Input: Consider Input: Although this is a wonderful working power adapter, I don't believe it is the Macally Adapter that was advertised. I am however happy with it and would shop with this vendor again.Thank you.

Output: Positive


Input: Consider Input: 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.

Output: Negative


Input: Consider Input: Dr. Bernstein is a type 1 diabetic and had just about every sympton possible. He figured out the "diabetes code" and clearly explains how to control your diabetes. His cure is exactly opposite to that of the medical establishment. He was educated as an engineer, then became a medical doctor late in life. His book is designed to educate and not to impress how smart he is. Buy it.David Smith


Output: Positive
