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!!!

Kyrobak If I could give this item a zero, I would. I really thought this was going to be an authentic device that would give me some relief and back pain. After only six uses, the interior mechanism, gears, whatever it is that makes it work, started stuttering and grinding. I only weigh 145 pounds so I know it’s not because of my weight. When I contacted the company to get a refund from Brand Street Market (brandstreetmarket.com)they refused without me paying for return shipping which is $37. Now, I can understand paying for return shipping if I didn’t like the item. However, this item broke after only one week and they expect me to cover return shipping. I am so tired of fraudulent companies taking advantage of people and our hard earned money. Do not buy this item it’s a piece of plastic crap. Do not buy from this company they are thieves and know they are selling crap.

Made my back worse Not for everyone and that should be explained- it is most definitely not for everyone and every existing back problem. Kryobak should make this very clear so as not to convey the false hope that it works for everyone and most certainly with the graphics telegraphing that message

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.

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!
