A shelf for the shower must be rust free. This works best with brass (how nice to read the reviews of the cheap 'stainless steel "models. And that just costs a little more. Absolutely top, I find that the manufacturers 10 year warranty on rust freedom granted. All right guarantee promises and statements Keep :)
Incidentally, I was glad that I have read in another review of a slight "deficiency". The small plastic caps on the back toward the glass stuck really it only very slightly. The very easy going back and forth from the slide and quickly lost due to the small size. I have therefore the same time glued properly.
