Make sure know what your problem is before buying Used once a few days after receiving and am still in excessive pain. on a scale of 1 to 10 I am experiencing on average an 8. I hurt so much that I failed to make the deadline for return of the device.

thanks for my purchase, but I have not made one Kyrobak have sent me an email thanking me for my purchase, but I haven't made one. They also erroneously put my account into the hands of a debt recovery agency!! Their records were incorrect. The first Kyro I got had to be sent back after 8 months, as it ceased working. It was replaced with no problem. I like the product very much, but not their administration and record keeping!!

Hard to believe Didn't really expect this to be helpful after years of chronic sore, spasming low back, especially after exertion. Surprisingly, I find myself using the Kyrobak at least once and sometimes twice a day. The motion actually seems to relax the muscles and substantially ease the discomfort. Not bad for only 10 min. of use!!!

DISAPPOINTED I had high hopes for relief of my lower back pain but after using the machine for 2 weeks I saw no improvement. I would have sent the machine back but I put it away and forgot about it and I think it was too late to return. For $300 I felt like I got ripped off. A total come on that got people to think they would get pain relief and then nothing. I have since then found a therapeutic massage therapist and she is doing an amazing job of stretching muscles and strengthening my body and I wish I would have spent my wasted $300 on more sessions with her. I recommend save your money and do not buy this machine

Unacceptable Unit came without the power cord. When I called to report it, the customer service rep. was incredulous then finally offerred to send a "replacement." There was no attempt to get it to me quickly so by the time it arrived about two weeks later, the unit had been stored and forgotten. In the meantime, I started doing yoga as my doctor had suggested to try and avoid a spinal fusion. I asked him about using this device but he was not aware of it or anything like it. He had doubts about how useful it might be, so I have yet to use it and will try to return it for a refund.
