I previously had a pure grey SI screen which works great with a standard throw projector. Then I found an Epson LS800 projector at such a price I couldn't pass it up. The picture was instantly better as you would expect from my previous entry level Optoma 4K setup I had been using for years. However, due to the extreme short throw of the Epson projector, I had some insane light showing up on the ceiling and side walls during certain scenes, as you would expect. Did some research and ultimately went with the SI UST material (my 3rd screen from SI). Are they pricier than most competitors? Yes! I guess they don't have that many reviews because people don't purchase them in the same quantity as the cheaper ones. I looked at numerous screens in our local ginormous store that has several paired with various projectors. None of them looked as good as my pure grey setup w/the Optoma projector, much less when I added the Epson. After quite a bit of research and consultation w/Zac from ProjectorScreen.com, I pulled the trigger and went with the SI UST 110 inch. HOLY SMOKES!!! Light splash on the ceiling/walls was instantly fixed!!! Much deeper black levels!!! Overall picture quality is the best I have ever seen on any projector screen combo! There are much cheaper options available, and yes, a few more expensive options. I could have gone with a ST screen for about half the price and probably had relatively good results, but this screen blows me away!!! If you are on the fence, don't be. GET IT!!!
