Although we like the style and finish of this set, we are disappointed with the mounting of the three non-towel bar pieces.  The mounting brackets have rounded edges and therefore it has been impossible to get the toilet paper holder and the robe hook to stay vertical.  They shift 1/4" to the right or left with just a little bit of pressure,  And yes, we used the proper hollow-wall anchors -- three of them in each mounting bracket.  The brackets are tight to the wall but the piece won't stay tight to the mounting bracket. The towel bars stay put because they have two ends.  We bought this set while we were rehabbing then bathroom, and so it took us more than 30 days to be ready to install them.   I would really like a refund but the policy is 30 days -- so lesson learned:  don't buy anything online early in the project.
