I got this screen as the first recommended screen was becoming increasingly unavailable, so a new screen was found that matched all features of the first and may be better in some cases. I am using a HiSense PX1-Pro UST.
This is my first ALR Screen, its easy to spot the attributes of screen tech here by how it looks gray one way and black another when just observing how the light hits it, in comparison to how your viewing it. How when your projector hits it, the light is re-directed back to you..
The velvet coating on the outer frame gives it a great look. Its pretty clear with some ambient light that this screen really optimizes the light from the projector.
Since I am a newbie in screen assembly, I am going to note that once you've assembled this for the first time, the complexity you may be leary of, assembling such an expensive screen, does fade as you go through it, and you really should have two people to insure the material goes in smoothly.
However, I did have some issues with the current iteration of the documentation. In Step 2, Assembling the inner frame, the picture labeled #2 shows a straight bar, which is also illustrated in Pics 6 & 7, that bar is actually a part of the outer frame assembly, and is not noted in those steps for being installed. That was sort of confusing, unless the screen design changed slightly since that doc was made, that might explain the confusion.
Also, more detail on the installation of the tension rods to highlight how short and longer ones fit into the sides and top/bottom of the screen would have been helpful. Also a little more detail in spring installation progression.. But once you get going it all comes together to create a great screen..
The adjustable screen mounts do give you the ability to make a couple inches of adjusting the height and insuring that the screen is level. The various dimensions noted for your specific projector as to how far it back from the screen and how far below the screen does determine how easily it is to align your projector to the screen.
This is a great screen and well worth the investment..
