“The device comes in two hard plastic pieces with a piece of foam in the middleThe two plastic pieces are supposed to slip into each other and then holdMy pieces of plastic do not hold and they keep coming apartAlso my chiropractor looked at the device and stated the curve on the plastic is far too long for the curve in your spineHe commented that the machine is badly and designedSo my advice is find an alternative”
“I have used it for only 3 days but am very pleased with the product . I really believe that with more use that I could easily give it a 5 rating in all areas.”
“I hate to write negative review, but I have no choice. In the beginning I was very happy about this item, it seems do the job perfectly. But it was the top of the iceberg. After using it for a month, I start feeling a strong pain in the back. And after I stopped using this massager pain stopped. I don't think you can use it until you visited a doctor. It's definitely not healthy for everyone, be careful about using without doctor's consulting.”
