Purchased promo (less so), even without much knowledge to use it. I have intense back pain (inflammatory spondylitis) and seeks to fight against these nuisances. Since there is no real treatment except immunomodulators that are not settled at all hazards. Since I try to use it as regularly as possible (ideally 2 times 15 minutes per day), its effects are not made against too noticed. For now I get tired too much for that. I read the manual at the same time :) No time to go to gym and dissatisfied physical therapy: this can only walk, movement and good personal support for the back muscles and the rest of the body are only to promise a slowdown the evolution of the disease. No need to purchase these devices "miracles" infrared etc. that cost a fortune to only partially used. As for slimming diets, there is no miracle: you have to take charge and move :) -dur-. The reward will come with regular practice. I chose to discover these trigger points on the advice of a very good physio. May not be suitable for everyone, better learn properly before investing in additional, I've spent so ago for solutions no future. It is painful and not very comfortable but promising :) Excellent device. our muscle fatigue and back pain. I use it every day for recovery before doing stretches.
