After about 5 months (on a perfectly smooth tile) came off the holder. We have converted him (on goodwill) and the new offset slightly (you never know) attached. But this broke up after about 4 months.
In fact crumbled in both holders first the locking screw on the inside, so that the holder wobbled. Even after repeated tightening shook the holder after a few days. By jiggling so my guess is the base was additionally charged to the holder ultimately broke away from the wall.
In my opinion, would be the adhesion force between the wall and base enough to keep the towel rack. But the base itself, that the fixing by a small screw inside holds, the weight (and especially the off and hang up the towels) in the long term was not.
With all other products of the series we are largely satisfied. Negative to mention, however, still would:
1) The rusty toilet brush in the region of the bristles, the dark spots occur. This looks the brush, as if it were dirty. We have therefore replaced the brush with another model.
2) Almost all accessories show after approximately 1 year small rust / corrosion-spots. While this falls to only if you look closely, but at the price I would not have expected.
