I ordered the 80" version of the manual B screen and highly recommend it. We have a small den, and this size was perfect for my new Xgimi Horizon 20 projector. Colors appear bright and vibrant on the screen, too.
I needed to replace the original spring after my kids had messed with it. I like that they make sure the piece is the right one by asking for serial numbers. The first replacement part unfortunately didn't work (it would not lock in place when pulled down), but after a single email they sent me another one which worked perfectly! I'm glad they were so responsive and fixed my problems without hassle.
I had a basic pull down screen for my projector that was ok but didn't really stand it. The cinegrey fixed screen is a significant improvement albeit assembly was a bit more challenging than I expected, and I enjoy putting things together (make sure you have plenty of room on all sides when assembling, it will make life easier) and, not surprisingly at this size, it was not an easy mount without assistance but with patience it worked. Firstly, at 120" it allows my projector room to display it's capabilities. The grey disappears on the direct viewing that I have it set up for and it really shines with 4k Panasonic videos. I find it a little distracting however for lower quality projections as the multiple pinpoint holes in the screen do not always disappear from view. I did expect it to provide a brighter picture based on the descriptions of how it absorbs inspect light but reflects back direct projected light but, it is not bad and I can view easily with all the lights on, though I don't given the improved picture when I only have a necessary light that is behind the projector.
