Used with the supplied silicone adhesive: no adhesion problems in position "corner" after three months of use on tiles previously been properly cleaned. The plastic used seemed a bit fragile at first glance, but once established, it does not move. The buttons provide resistance measured pressure, finally bit embarrassing even for use by children. The system is convenient and allows probably make some substantial savings product in the long run. Located near the shower, the few traces of limestone that are deposited not more difficult to remove than the rest of the shower system. Very happy with the purchase, I wish I could complete it with the model "right", oddly much more expensive.
