At first we were very satisfied with this neutral and unobtrusive doorstops. On tiles slip it partly like to, but in the bathroom you need it not too often. In itself, so everything was fine until then only two of the four rubber rings are broken within six months. After that, the stoppers are not really well suited for use, since the doors now just come across bare metal, which is both noisy and not good for the doors. The quality is not exactly optimal, even for this price.
