I have tried the demo version of this product in stores and thought it was great. I was happy with the price I found on Amazon, so bought it, but am more than a little dissatisfied with the product I got. I was supposed to get new, but what I received was obviously opened and unpacked previously. I set it up exactly per instructions, but the motor seems to strain, and it sounds sort of sick. The massage is poor, and does not even go up to my shoulder blades, so misses the entire top of my back. I don't know if I got a dud or if it is just not as good as I anticipated. I am really disappointed and would not recommend it.
