The only drawback are the suckers. However, I have to say that we do not have high-gloss tiles on the walls but somewhat rougher imitates natural stone tiles. Keep it with us no suckers any manufacturer on the walls, because the build-vacuum by the minimum structure of the tile. So I do not see it as a product fault.
I have the power now fixed by means of transparent Tesa Strips on the walls and it pushed through as decoration nor the suckers with the ducks. A photo for this purpose I upload. It holds bombproof despite full power and can be detached without a trace.
