So far I have had good experiences with the product. I own it now since about one month and would highly recommend it. I turn the rollers and balls about 3-4 times a week and my complaints have really improved. I use the small role of the sole of the foot, the balls to the gluteal muscles to work and the important role mainly for the outer thigh, as well as for the back and shoulders. Over a longer time I have under the so-called. Tractus-iliotibialis syndrome suffered and use the rollers in addition to physiotherapy and my Akkupressurmatte. As the complaints now be without physiotherapy and Akkupressurmatte, I do not know, but I think the roles a good addition. Whether the DVD really needs remains to be seen, there are plenty of videos on the net showing the application, but I found very appealing overall package and it would buy again.
