Nice heavy duty unit that looks great. Mounted through drywall but because I was renovating, I was able to put backer boards behind drywall so I could screw into solid wood. Not sure I would like the plastic plugs that came with kit because that door is one heavy baby.  The only thing I will address is replacing the stickers used to cover screw holes after assembly is complete with plastic plugs that can be found at a hardware store.  Assembly was no problem. Keep in mind that it comes in two packages (the frosted glass comes separate from the rest of the door and hardware). My two packages came about 10 days apart. I called Wayfair after first package arrived and they were great tracking down the other package and making sure I was notified that it was coming. Best customer service going!
