I recieved this kit in two large boxes on a Thursday morning. Worked on it about 4 hours Thursday and got it completed by Friday evening by myself. A few steps are tough if alone, but I was able to complete. Very sturdy. Good hardware. You'll definitely want to get a socket adapter for your drill to save massive time - also the tools provided are, well, free tools. I used two of the steel straps that came with the packaging to make cross trusses for a ceiling fan - works great. Steel roof panels get very hot in the sun and can radiate some of that head downward. A fan pulling air up and out the top vent really makes a difference. All around, I'm very satisfied.
