I purchased 2 of these houses about 5 years ago. I had no problem with the assembly. It wasn't as easy as the square alum houses but still wasn't bad. I take these down and clean and store them during the winter. The only problem I have with these houses is that the rails to hold the baby martins in keep falling off and getting loose. I have fixed that problem and replaced a lot of them with wooden railing with screws. I also have a large wooden house and I know it's much cooler than the metal houses. Both are fine. Wooden houses are more subject to disease and lice unless it's built out of cedar.
