The Beurer has only one massage head. But the do just fine. The engine vibrriert not only easy, but the massage head moves up and down actually - knocking flat. The speed at which this happens can be regulated infinitely. However, the strength of the tapping motion is always the same. Meets the massage head "perpendicular" to be massaged muscle section, the depth effect is naturally at its greatest. But actually that's not always sensible and can in the long run even more cause pain. But by holding the massage head more or less inclined, you can do against dose the effect fine. In addition, you get the only way to benefit from the thermal radiation, which release the mounted fairly high up above the actual massage head Infrared lamps. Anyone who wants to can "knock through" by Breuer system like a jackhammer can - well recommended only for very tough cases. Alternatively, the user can mitigate doses the knock effect by tilting the massage head. In my experience, a slow speed knock acts intense. Higher speeds are a little gentler. All in all, the effect of considerably more than with my old vibrating massager.
One drawback has Beurer device, however: For a significant knock effect can be achieved is a certain mass necessary. Specifically, this means that the system is quite heavy. However, the center of gravity directly above the massage head while the handle is quite easy. This mass is hardly noticeable. Longer massage sessions, however, are something tiresome.
Personally, I would massage the system no older, possibly infirm person. But the knocking effect is too strong. Suffer For all other individuals occupationally exposed under tension such as the neck (Schreibtischtäter up) or in the calves (marathon runners), the thing is highly recommended. In future I will only pass a sniff of the vibration massage devices - and be priced no matter how attractive. The slightly higher cost of tapping massage have all worthwhile.
