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.

The Kyrobak Please be advised that the Kyrobak was a waste of money. I used it according to instruction and it did absolutely nothing. I tried contacting the company and couldn't get though, so was never able to get a customer service rep.

Hard Lesson Learned Anyone who has even mild back issues should NOT use Kyrobak. I have experienced a "shift in my spine" after using daily for two months. I really wanted it to help, but has landed me in worse shape. Dr. said I should never try something that has not been studied. Hard Lesson Learned!

useless When i say useless.....well thats what it has been for me , i suppose it all depends on what you think it might do/or cure? I was way out of line with this machine , it has done nothing for my chronic / acute back pain. But it has enlightened me into reading too much into claims manufacturers of such machines state. Reaserch real evidence before you waste your money on this item. It will just be another unwanted " hope " i might eventually donate to a charity shop / or recycle bin .................for me ........a total waste of time.................good luck . i hope your pain is not too bad..Donnie

wschaeff's review I found that it really didn't do much for me. At the time of use, I really didn't have a problem but I found that, for whatever reason, after using it for a while, I began to feel some discomfort and so discontinued to use it. I should add that when I ordered it, the advertisement led me to believe that it was a good deal less expensive then when I was billed. You should review that.
