The holes for the door stopper were too small for the piece that goes into it, but it was a quick and easy fix with a drill and putting a screw through the middle to hold it in place. Also the stickers that come on it peel off the paper that makes it look like solid wood. Luckily this only occurred either on the inside sides or the bottom piece. Overall it feels sturdy and I like the look, hopefully my cat likes it. You will need a power drill to do this build.
