We were looking for a good massage mat, as we were able to test the mats Homedics in an electronics store. After extensive research, we came across this model, which looked similar to the image well. So we have it summarily ordered and equally tested. The mat was packaged very well with us, and made from the quality also a good final pressure. All very high quality! Then tested the mat on a chair (one should not really because too soft), which of course did not work well. So the kitchen chair was my turn. Here it was noted that one had the mat at the back move up slightly so that it comes well to the shoulder. Device connected to the power and tested the demo program. The back massage was very firm and hard, our feeling her somewhat too tightly. Unfortunately, the shoulder blades are not massaged clever, the balls do not go as high. But that was one of the main reasons why we wanted such a mat. So the unit went back to Amazon again and we enes days later bought the Homedics CBS-1000. These cost more than twice, but it shows a distinct difference! The device is similar in principle to that of Medisana, as well packaged and processed, just massage the balls and the shoulders, because the back is higher. Unfortunately, this also managed not cheaper models of Homedics (SBM 500 and 600).
So before 500 or 600 spending money for the Homedics SBM, certainly with this mat of Medisana quite well off. But who is looking for a really good mat for all the back and shoulders, can not ignore the CBS1000. This can be by the way also attach to chair!
