The quality of material is very good and provides several different wheel placement options However, I’m giving this a 3 because out of all the adjustment options, I was only able to use just one wheel and this was just so my door wouldn’t swing outward. The wheel that would be on the back side of the door stuck out too far and I had it adjusted as far as it would go inward to wall where it was mounted. With the back wheel on it caused my door not be vertically aligned Essentially the back side of my door is scrubbing bracket.  My door is already hung with a backer board so it does protrude outward I could possibly make it work by cutting out a piece of my baseboard so the bracket could recess further inward. I just haven’t tried that it yet.
