All are fabricated using highly specialized “blow molding” techniques similar to those used to form aircraft canopies. The result is virtually distortion-free optics. Made from the finest grade of 1/8 in.
I noticed that the screen was cracked during unwrapping. Shipping cost prohibit returning it so I went ahead and started to install. It cracked again twice during install. It says in the instructions not to over tighten the screws but this is ridiculous. It took no force at all for the mounting points to break. The material is thin and brittle compared to my other screen. Even though it probably does its job, I would not recommend based on the product quality. I don't expect this screen to last very long. Waste of money.
