The slip mat consists of a bathtub liner and a neck pad and both are easy to attach to the bathtub. However, the knobs are very rough / big, so they noted the shower or lying in the bath. In addition, many knobs are indeed sufficiently attached, one can not pass from slipping so, but they are always in a certain range, so that one certainly notices the knobs. If these better distributed, which would probably not so much notice. 4 stars there yet, because the deposit is very good anti-slip and the neck pad is really good and comfortable. The headrest is more cushioned and has the knobs to secure in place. The look is timeless well and should fit in any bathroom.
The tub liner + Nackenpolster has collectively earned only 4 stars because, although fulfill their purpose very well, but the insert itself through the "large" knobs is slightly uncomfortable.
