Due to the numerous positive customer reviews I've bought the Mediflow water cushion. As other customers frequently reported an almost unbelievable effect against neck pain, I had hoped that the pad would work wonders with me. Unfortunately, it was not like that. After trying out different quantities, in parts also short satisfaction and the experience that other cushion not alleviate my symptoms, I no longer use the pillow now. In retrospect, I have experienced no relief, sometimes even a morning wake up with a stiff neck. My impression is that the pillow for back sleepers is more appropriate than for side sleepers.
The good quality of the pillow is unquestionable - but you should not leave by the many positive comments regarding the dazzle effect.
