the box itself like it very much. it has plenty of room to drill for all walls kept clear and is to be labeled more appropriately.
on the back is space for different anchors or screws directly to store.
In addition, the box is also equally supplied with a choice of anchors.
So in my opinion a very good box, at a reasonable price.
Only if you want to be prepared for harder material, you should to buy additionally appropriate drills.
