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: My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.

A: Positive

Q: After repeated washings, it still smelled like a toxic plastic and who wants to put toxic plastic inside their body. Also, it didn't do the job. So I wasted my money and had to throw it away.

Negative
