For a year now I am enjoying my pillow, and since then it's much better to me. I wake up refreshed and can imagine no other pillow to sleep more.
Now I have already ordered the second pillow because my pillow has been my husband who has neck problems appropriated, and now want to sleep on any other pillow more.
At first, I had to first get used to the pillow, because you sleep but otherwise than on conventional pillows. One can not, for example, the pad "zusammenknautschen" what I have always done in general with my old pillows. But that's not necessary, because the "miracle pillow" automatically adapts to the sleeping position, and is therefore always perfectly aligned. I have experimented with the filling until I found out the optimum for me level and am fully satisfied now.
Depending on the desired degree of hardness can be the pillow with 2-5 liters of tap water filling using a funnel. The water can then remain in the cushion up to one year, after which it should be replaced.
If one considers the filling instructions, and the residual air is completely removed, can be any noise that might arise through the water during the night no time avoid.
I especially like that one the pillow, when the water is out there (it is filled due to the water very difficult), even super can take on vacation, and therefore nowhere have to do without the sleep comfort.
From me an unconditional recommendation to buy !!
