In general, the quality of the product is very good. Everything works just as described, I have no defects.
There are the Shiatsu Massage, since the wheels are spinning circular, and the role of massage, here the rollers slide back gently back and forth. The bolsters may only Shiatsu, not roll, which also does not follow so much sense, and remain at a height that can be adjusted by remote control. So do not go up and down, as on back.
The rolls can be heated and then glow red (looks pretty cool). Until the rollers are really warm, it takes 2-3 minutes, you can also be really hot (burn does not do that, but too hard you should not press against it after a certain time. It should, according to instructions no longer than 3 minutes get a massage with heat the same spot.
Man can either the whole body, just above or just below masssieren leave. This applies to both types (Shiatsu and rolling).
Basically, the device is divided into two. Namely in the back part and the neck part.
Since the only difference to the half as expensive 300 model are the bolsters, I would like to address special attention in order to assist in a possible buying decision here can.
Well, the neck massage pays off? Yes and no.
If you just so it continues, the bolsters do not come to where they should go. In normal position, however, they did not reach the shoulders quite well, the neck / throat area, because the roles are too far apart. Therefore, one must always turn to one side (So only one side can massage), then back to the other side, etc. This helps then quite well - my neck muscles are much more relaxed than in the past - is cumbersome (and takes twice as long as only one side can be massaged).
The back wheels do not come up as high as that of the 300 model (without bolsters). For the bolsters come very far down in the shoulder area. Nevertheless, a small space where neither the back - even get there the bolsters.
My recommendation: people who have strong neck problems, the device should buy despite the described shortcomings. People who have more back or cross complaints, I recommend the 300 model. (This protects the wallet, thus preventing from the outset cramped muscles ;-))
Finally, I would like to say that I can not leave on the chair the device when not in use because it is very uncomfortable otherwise. It takes but a part of the seat away, therefore is suitable for normal to large seats, chairs, armchairs, so the contact area should be big enough so that you then also still in there place has ;-)) One must therefore always put away ( unless you have a separate chair for it).
