Have the Kisen just unpacked and was shocked really. The cushion krümmelt without end, I do not know what there anything "sandy" fall out-one can equal ranholen a vacuum cleaner. Even repeated shaking does not help here. Furthermore, the grains are totally sharp, what I have never experienced before. I have bought countless Körnerkissen in my life, because they are several times a day with me in use and sometime they have it behind you. Even the material by the grains are totally rough leaves -What close to cheap quality. Is the money (shipping is for some also still added) absolutely not worth it. I will send it immediately back Monday. I have the same size of the pad currently in use and, unlike this one, it is really soft, as you will notice the difference immediately. However, those looking for a slightly different acupuncture, for it would be great, just let drauflegen and pieken; o) Thumb Down!
