As far as image quality, this is as good as it gets for a darkened room. However, you get what you pay for and this required some extra engineering to make work. Normally, I would not give such a great review, but the price just makes up for it!
First, the screen is a little too wide and there is not enough stretch horizontally. I fixed this by marking the left and right peg positions and then removing them. I then used 1/2 inch self tapping screws placing them half way between the peg grove and the frame edge. MAKE SURE not to drive them in all the way as they may come out the front. I never did so I do not know if the would or not.
Second, the horizonal stretch bars come in two pieces and the joint easily cracks. If this happen to you, use a piece of 1/4 inch Poly Ice Maker Supply Line to replace the union. It is not as stiff as the original joint but it got the job done and will not snap.
