The wall mount on these Moen Eva towel bars and rings is a poor design.  If it doesn't click into the bracket just perfectly the first time it remains loose against the wall.  We just removed the towel bars after half of the one fell off the wall and replaced them with ones that have the normal wall mount brackets.  We have Moen Eva thorough out the bath, and I love the faucets and shower heads, but I would not recommend this product.
