The paper holder seems to be of mediocre quality and, unlike every other similar holder, the arm is fixed.  The mount to the wall is fairly soft plastic that will most likely not hold up well.  Most importantly, the plastic mount is secured with only a single screw and two metal tabs that poke into the wall.  Given the leverage that will be applied during use, the toilet paper holder will spin on its mount and will be somewhat useless.  Will be returning.
