I was allowed to try out the product as part of a product testing. The application is simple, spray with a spray bottle and wipe with the supplied cloth Vileda. (Unfortunately a bit small) The fixtures look like new, the water runs off better, but at my very calcareous water is not as promised, but looks after two or three days off again as before, only the deposits may be somewhat less pronounced than without use of Vileda Magical. In the mirror, I had the problem that he looked smeared on the application and I would rather back regularly brush than with the product. Overall, I think the lotus effect is too small, I could not, unfortunately, it clearly detectable. This has disappointed me. What makes me a little concern, is the statement that you will not breathe in the spray. How will that work if I'm in the shower - hold your breath? And what happens in my lungs? I give deduction of points, because I could not use as expected the announced product properties.
