Gets The Job Done
We got this for bathing our dogs in the tub, never having a good spot to place the handheld shower.  It does the job.  Yes, it does stick out a bit, but just put it in a spot where it won't bug you (ours is above the bath spout).  Or, take it off when not in use.  It's an easily attached suction cup, so we're not talking hours or even minutes of work here.  Through a few tests/uses, it only cam unstuck once, but that's simply because the hose of the shower caught it and pulled it off.  Aside from that, we've had no problem with it staying put.  I went with the clean-and-dry suction method, which works best on our 5x5 inch tiled shower.
