It’s perfect for what we need. Instructions are easy to follow, but you need to pay attention carefully because some of the pieces look the same but holes for assembly may be different. It went along easily as we assembled the base and walls, but then we got to pieces that had a plastic wrap still on them. Seriously, pulling that wrap off was harder than assembling it. Those things were very stubborn and some of them I could only get little pieces at a time. All in all it works well for our needs but I sure wish the manufacturer hadn’t sent it out with protective wrap.  If it was for scratch protection it failed. There were scratches, and little dents. Nothing serious. The panels weren’t consistent. It’s as if it went through the excluder and didn’t quite get the stamp correct. Some are flat and some have grooves. This isn’t a big deal for us, but if asthmatics are your thing you might be disappointed.
