I assembled and installed this today and very pleased with the product.
I did all of the assembly myself, but got help to hang it on the wall. Assembly took about 1.5 - 2 hours from unboxing to completion.
** You need a very big, clear floor space to assemble this! ** Anticipate requiring 3ft of clearance on each side as you insert the tension rods (you can carefully slide the frame around to gain this clearance as needed). I assembled mine on a carpeted floor in an area about 14ft x 14 ft.
The directions are clear enough, and warn you when to expect a challenging section (of which there are only 2).
Everything is quite simple except for 2 parts: 1. When you go to stretch the screen material over the plastic pegs. The instructions tell you that the vinyl will stretch and that it will fit - and it certainly does, without problem. But there is a moment of uncertainty while you are stretching it when you think to yourself, "there's no way this is going to fit." But it does, without problem. 2. When you go to install the middle support beam. Ok, I'm lying. Others posted that they had massive difficulty or trepidation while installing this last piece. Actually, I had zero problem with it at all and I did it by myself. It took about 30 seconds to slide the bar into place. I don't know if I got a "good" kit or if I just took my time to get all of the parts properly installed as I went along. In any case, I had zero problem getting this crossbar installed.
The quality of both the frame and the screen is excellent. The assembled product feels robust, not flimsy. Colors pop and the black velvet frame diffuses overscan perfectly.
