Shortly beforehand, both my wife and I both suffer from "cmd" a TMJ history, from neck problems as a result. we try for years always new cushions, and have never found the right. headache again in the morning, tension, sleep through no etc. then we got the tip to this water cushion. who first ordered one, I was the guinea pig. after 2 weeks, we have bought the second and what can I say ... we both like babies to sleep, barely problems with the neck. you have to initially experiment a bit in terms of capacity, but after a few nights you have found the optimum for itself. I'll never again take another pillow and this traveling from ever take away today!
EDIT: After ten months, the pillow leaking and causing a disaster in the MID mattress! NOT RECOMMENDED!!!!!!!!!
EDIT 2: after 1.5 years is now the second break. But even worse than the loss of water, the formation of mold is wrapping on the! Dangerous for allergy sufferers and everyone else! I can only warn against this cushion !!!
