1-second install, easily moveable in 1-second, never falls off, strong suction - used daily - sooooooo worth it!
For $10 or whatever it cost, this thing saves my back and my 2 toddlers from having to hold a shower head and drop it and splash me and get the whole bathroom wet, and get yelled at.  suctions on with a clip in one second onto dirty, wet wall.  Super easy and strong hold.  Been on for 1 month, moved around daily to adjust height position for 2 different kids to spray a stream on them to keep them warm during shower and never has slipped off once, even with pressure and hitting it by mistake.  Most kids products never get used even 20% of the time and are money well wasted.  This is used in 100% of our preschool-aged kids showers and is cheap money well spent.
