I have the HoMedics massage pillow for a few days and am highly satisfied with the device. I got already often from a massage therapist a "correct" massage and can therefore certainly evaluate and compare the unit. It replaces a medical massage certainly not. This is also the manufacturer's instructions. Who has such excessive expectations of the machine, is your own fault! I can say that the pillow made me a very relaxing massage effect. I've tried it mainly in the shoulder and neck area, but also in the lower back, where it's a real treat for me. Although the device is really only useful for these areas of the body, I have also been used for foot and calf massage. On her feet, I find the massage super pleasant. Have put forward to our wrap around sofa, leaning the massage cushion against the opposing back and pressed my feet against the pillow, as it was pleasant for me - lovely !. At the calves I'm a little too sensitive, so it is not so suitable for this purpose, at least for me, but that should probably try any myself. Total incomprehensible, I found the criticism of an earlier reviewer who has "put on the pillow" and then complained that the "brutally hard" massage buttons were painful to his back and could potentially cause injury. Since I can only shake his head! On the one hand I have this variant being tested even once and found it not at all painful. On the other hand one must also say that in the owner's manual is not a word about the fact that one can lie down on top of the pillow. The pictures suggest that you should lean against merely! So if you used the pillow inappropriately, who need not be surprised if the effect is not desired! I can even say that it has a handy size, the reference is pleasantly fluffy and the cable has a good length to the device itself. In the heating function it is necessary after switching actually wait a little while, but then it is very pleasant. The switch is well hidden under the cover, but still good to use. An accidental contact of the switch while the unit is in operation, is actually unlikely. If you do, it is also not the end. Simply press the button again and enjoy more ... The only reason I forgive only four stars, is that the left button massage a little rattled at delivery as opposed to the right. Meanwhile, this is also when the right button of the case. Also makes the device when I use it, easily cracking noises (I do not mean the hum of the engine!), Which is at times a bit annoying. I am very unsure if this is normal and had only considered return the pillow and have it delivered me a new, but otherwise everything is to my satisfaction, I will keep it. Let's see how long I'll have it pleasure ...
