stays up but not green as shown
The shower arm fits on a tile surface that is 4x4 so that it stays put.  I placed it where i won't have to change it's position too much so that there's no wear on the rubber that suctions onto the wall.  It's been sveral months and is holding up so far.  The only thing different from what was pictured is the lock is not green as it looks nicer that way but it's grey, otherwise it works pretty well holding the shower head up.
