I'll start out by saying that projector screen.com has some of the best customer service I've ever experienced. They're a knowledgeable sales staff, and the owner, Brian, has great customer relation skills.
That being said, the screen is a pain to put together. However, the end result is phenomenal. The picture clarity is amazing, and I think you would find it difficult to compare it with other screens. I was originally looking at elite screens, aeon, and some foreign made items. I'm very glad I went with this one. I docked one star from the review because the instructions that come with this are written by somebody that English is a fourth or fifth language. I'm not sure if this was ever even peer-reviewed by somebody on the English speaking side. They may have changed the instructions by this point, but when I was putting it together I had a horrible experience.
Not to toot my own horn, but I'm pretty handy with things. So, after reading the instructions, I kind of had to piece together what the instructions actually meant and go from there. The mounting system for this was horrible. I think it could have been executed in a different way that would have made this much easier. A rail system with easier adjustments would have been a great idea.
Now, the reason it's got four stars instead of any less was because the picture is absolutely amazing. Paired with the Optoma P2 this screen blows your mind. I've had so many people get lost looking at my TV. When they see the wall, they have no clue that the screen is going to turn into a mirage of images that would cause even the most anti-electronic person to take third and fourth glances. I attribute this to the projector itself, my expert calibration of course, and the craftsmanship of the screen.
Even though the installation of the product is maddening, the end result is so worth it. If you're looking for a screen, give projector screen.com a call. They'll steer you in the right direction. If you don't want to call, just buy this screen. You will not be disappointed in the end even if there's plenty of cursing in between. Some quick tips. Get the stand that you want for your projector, or at least the height of the stand first. Then, put an image of a test pattern on the wall. Mark the test pattern with tape. This will be where you install the actual screen. prior to installing the screen make sure that everything is level and square to where you want it with the test pattern. If you don't do this, say if your floors aren't level, or your ceiling isn't square, you will end up with a lopsided image. It'll still look fantastic, but it's not going to be square with your room if you're sailing or your floors off. I know from experience.
Once you have everything set up, I'd rather live with an unsquare looking setup, then try to re-level the screen and change my projector stand level. Trust me, get the stand, The projector, and the test pattern exactly where you want it on the wall first. Then you can begin assembly and mounting.
Oh yeah, if you think you're doing this in a couple hours, good luck. Block out about 5 hours or more if You have problems assembling things. I did everything slowly and precisely, and I'm thinking it took about 5 hours. I still messed up. Good luck, it's worth it in the end.
