Suction cups for mounting? A big joke

Have bought the product and was initially pleasantly surprised that I have to drill any further holes in the newly tiled bathroom, because of the mounting suckers are mitgelierfert. But turned out to be huge joke. The stop at the tile not even their own weight and fall after a few seconds of self to the ground. Not to mention that they still should keep the towel rail. So around the drilling you will not come around. In addition, the product is one that can handle the "reasonable" price quickly.
