I purchased this 9/13 and it has worked very well for me.  It has only come loose once during this time except for when I repositioned it.  I have it on a fiberglass shower.  The angle is fixed.  It can be turned in the bracket to go right or left but cannot be tilted up.  I am buying another one for my daughter to get the shower nozzle in a lower position.
