Actually only 1 star, but the pillow is well made and "works" as is well thought.
However, one feature that seems to have not fully thought through. If you have tried the pillow times, you quickly realize the water is completely inadequate to support the head. It flows namely easy sideways relative regardless of how much or little you purely fill in the pillow. The result is that you can then located only on the fabric (very low), while the blown a cushion enclosing the left and right head (stupid breathing).
If one makes the other hand, the pillow really crowded, so this effect is no longer there, and you can actually located on the water, the pillow is brutally hard and also very high.
In addition, it has probably taken a more moisture-resistant material because of the water, the result is that I'm on a sweaty pillow case after half the night.
Last issue of water, the pad is very difficult. During the turn the pillow cope push, is not.
I guess you would have just made the water bag in pillow half its volume, would work the whole better.
