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

So far no discernible benefits There has been no miracle cure so far or even any improvement in symptoms. Obviously it has done no harm and maybe it is too early to see a big improvement. However my wife, who bought it for me, insists I continue using it!

Not fit for pupose. I try this for about 2weeks and during that time my ability to walk was greatly reduce and the pain I was in was unbearable. I had a rest from it until I was in less pain and could walk a little more. On the second try of it I only managed a week. I phoned to find out how to return it and get a refund (I was not worried about the extra insurance I had taken out on it) I was informed that lots of people have found it useful and I could not return it and get a refund. I told the girl I was speaking t it was not fit for the purpose it had be sold to be and basically was tod tough try and sale it privately. So I would say stay away from this as it does not work it makes matters worse and the customer service is rude and unhelpful. The chances of get you money back is nil.

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.

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
