The other day I walked across the Tödelmarkt and had a massive muscle tension in the neck. This must be well have seen clearly from the outside. Because there is a little man with this little Massagegeät up to me and asks if he can help me. Before I knew it, I had my massaged away with the "thing" the distortions in minutes. I was erstaund - I would not have expected the small device - but where all other major had failed, including my doctor. He wanted 20 for it and he got by me ... Later I the device a good friend of mine introduced with equal success. The device massaged on two points exactly and not so extensive and unfocused as others. In addition, the two AA batteries keep surprisingly long. In addition to mobility, you can always have in your pocket. Later I got it at Amazon .incl. Shipping get ordered für14,20 Euro and delivered that it is all worth it! The "things" probably come from Korea, but it was something of me no matter - helped it and very good ... highly recommended it!
