Caution!
Not made for long durations, only for several minutes.  Mother in-law made a mistake to leave it overnight with the shower head and it fell off.  A little inconvenient for elderly use with arthritis and bending issues.  Someone has to mount it for her.  I wish it would stay on for longer.  Once it mounts its very sturdy.  Which is why i'm not sure why it would just fall off after a set duration.  Will time it and update review.
