"After reading the reviews here, I was hesitant about buying it - especially the concerns expressed about the chain link. But - we couldn't find one locally even close to the price, and Petco assured us that if it came missing parts, or defective, they'd back it up.
The frame goes up easily - pay attention to the recommendations on the instructions (like not putting the door over a joint - although that was easily solved by putting a self tapping screw in!) For the chain link fencing installation - I recommend a flat surface, like a driveway, plenty of room around the frame, and two people (one to fasten the fence to the frame, and one to keep the fencing upright). It took about 2 hours, but I'm slow;-) I had no missing parts, and while some of the chain link loops were un-hooked from each other on the top & bottom (and some were also un-wound a couple of turns), with a little patience, all of that was easily solved - again, it goes better with two people.
The instructions recommend a 9/16" and 1/2" wrench - I kept a 10mm socket handy, because the 1/2" bolts have galvanizing on them, making them a little thicker than normal. And - if you opt for the UV cover - gentle on the tie wraps; over-tightening them will break them.
Good luck!"
