Have had the massager for about one month now. I have some less than perfect disks in my lower back. It took a bit of practice to get it set to the best height. The height markings on the dial are supposed to correspond to the user height but didn't match the height I needed so I had to raise it up a couple of inches. But once positioned correctly it worked well. I get relief when I use it that stays with me for several hours. Shipping was prompt and setup was pretty easy. Item received was as advertised.
This is my second Back To Life machine and I use it daily. It has done wonders for my back. This one was like brand new in the box, except there is a small knocking noise when in use. it does not stop the machine from working well, though.
What a life saver! My back pain has decreased with every use of this nifty massager, and the best thing of all is that it's a passive motion. It's not an exerciser, it's a massager. It doesn't work for everyone, but it worked for me!!
