First of all, who has back problems, should first consult a doctor once, and not to self-medicate. Depending on the symptoms may rest hip, a special back training or just simply a massage, as it allows this device in some way. This back trainer is useful to solve slight tension and blockages in the lower back, at least mitigate. Who vertebral damage or a herniated disc, I would strongly advise against the use. At first I was skeptical about the benefits, but since I've already been a long time in a so-called. Chiro-therapy, in which also solved the blockade, massaging the back, was directed and stretched, it is called there "adjust" I tried it a try with this unit. Pricewise it is approximately equal to three treatments. For me the device, especially if I use it every day really works. Immediately after use / massage I noticed any tension and hardly any pain in the back. The device is in use really a bit noisy, this rotating sound of the engine is quite disturbing. But I mostly listen to music on headphones while I use the back trainer, so it does not bother me really. Over the life of the appliance can be after a few weeks too early to say much, but when I compare the price with the cost of treatments and massages for a similar period, then I'm already far in positive territory. For me, the acquisition was worth. Because of the noise a star deduction, but two stars would be too much, because it does not really bother me, and helps me continue the instrument in terms of function.
