The cleaner has initially done exactly what it promises - and the admittedly very good. However, it has been easily solved after about 1 year, the outer fabric coating of the magnet, or moved, which I did not think anything and the adhesive sheet fixed again. Unfortunately I acted myself in the following period by 3 relatively deep 15mm long scratch on the outer pane, which is no longer to be eliminated with all the tricks (eg polishing). No time is not because it is a 230l- Eckaquarium. Therefore, I now always look at the scratches. I never thought that one glass aquarium can be by plastic as scratch! Tip: If you want to use still the part, both magnetic parts preserved as possible not zusammengeklippt jointly but separately, so that the coating can not slip!
