No way I’d give this five stars. And I struggled to give it four to be honest
Once it’s installed it looks great. As someone else had mentioned the instructions are pretty useless. This item comes with screws and wall anchors. If given the chance, install into studs or use different plugs. The ones provided are terrible. I wanted this shelf unit centered in the wall where it was hung. To do this, I had to use the anchors, and not really giving any thought to it, opted to use the ones provided. They flat out suck. So, I then opted to hang it off center into studs. I wish I had bought this item prior to doing some renovations because I would have installed some blocking in the walls, but it is what it is. So, in closing, I installed a 2-shelf version that does look nice once installed. The instructions are basically useless. If using wall anchors, find better ones. Choose to install into studs if possible.

This is incredibly difficult to get the holes lined up
We tried a few ways to install this. It was incredible difficult to get the holes lined up and the drywall screws were really poorly made- they went right through the wall. We were able to get 3/4 screws on each hole lined up. Better written instructions would have probably gone a long way.
