I use this water cushion continuously for five years now. Before that I tried diverse pillows and no I was so pleased with how this here. Granted, everyone has different demands on the subjective comfort of a pillow and some people do not like the slight rocking of the pad. I like it. I have filled the maximum water capacity of five liters and exchange the water about twice a year. So far I had no problems with leaks or misting water. Should this looming in the near future, I'm going to buy this pillow with security again.
