Due to a desk job and entsprechenem sedentary I suffer from tension in the shoulder and neck area that have not improved by acupuncture, physiotherapy and osteopathy. Even now that I do a lot of sports, unfortunately, does not help. In recent years, so I'm rid of a lot of money, but still have the same problems. In a newspaper article I was then aware of TENS and have immediately informed times and then ordered this product, because my products from the retailers were simply too expensive on Amazon. My conclusion after a few weeks of regular TENS Massage: My tension although not gone, but has improved considerably. Above all, I do not feel so shipped, but know that I can do something very active against my tensions. If my neck pinches again after a stressful day at the office, I just stick my electrodes to the skin and invest 30 minutes in the TENS massage while I cook or clean up for example. Thanks to a practical belt loop can be the device that is easy to carry with you. The electrode hold despite 4 weeks of almost daily use by further and stick like the first day, even though I have maintained zero (in the instructions, they should with clean after use with a lint-free cloth - I am too lazy, because I order rather new electrodes). The only thing I regret is that I did not buy the device rather a lot. My tip: I have not bought a large moor pillow of Wurzelsepp (38x25 cm), which I warming up after TENS massage in the microwave, then put on the tense spots. The combination is really highly recommended.
