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.

problems with kyrobak 1. the product is overpriced. it seems like you are preying on people with medical problems; it does work, but not to the advertised amount. 2. the guarantee Is so complicated that it is almost impossible to follow. 3. my first kyrobak was defective. the return process, and getting a replacement was so cumbersome, and length (almost 3 months) that I now have less trust in kyrobak to keep my information confidential, and that if I do try to return I won't be able to. 4. re: 3 above, kyrobak didn't send me a replacement, and until I badgered them enough they finally recognized that I had paid for a kyrobak (they had no clue who I was after I returned the defective machine) and had returned a defective machine. I was totally unhappy about their bookkeeping, and honesty.

Not a useful product. The Kyrobak did nothing to alleviate my low back pain, so I have returned it pursuant to their 60-day money back guarantee. I do not recommend Kyrobak.

notice of improvement I do feel there has been a noticeable improvement in reducing my back pain. It isn't completely gone like I had hoped but I am certainly more comfortable than before staring to use it. I am hoping I will continue to see improvement by daily use either once or twice a day.

Kyrobak I'm sure this is very effective for most people. My problem is my head needs to stay more elevated than this allows to be effective; otherwise my "crystals" get out of wack and I get very dizzy. Also, if you are alone, getting on is a little difficult, and I tried to reverse that to get started, but that did not work.
