My building was constructed in 1926, and the bathroom is all original fixtures, so I hate using anything cheap and plastic looking there.  Unfortunately I also have hard water and metal seems to rust so quickly, even if it is a shower fixture that claims to be never rust.  I was delighted to discover this solution and look forward to never replacing my shower organizer again!  It looks gorgeous against the old subway tile, has plenty of room for all my stuff, and definitely won't ever rust!  It's beautiful and looks to be very solidly constructed, the rubber holder to keep it in place is ingenious, especially for older and non-standard fixtures.  

Pros: appearance, durability
