I bought this screen for a school event. While it worked well, wind was definitely a problem and I'll get to that.
The good... The screen feels of good quality. It's easy to assemble. You have 3 components, 2 stands and a top bar, that interlock (with the base being screwed on with an included hex wrench). The screen itself slides onto the top bar and then velcros onto the sides. The base of the stands are nice because they are FLAT and not a tripod design, which makes it easier to put weights on to keep the screen stable.
The screen itself was good quality. With a 2000 lumens projector, I was able to get a clear image with both front and rear projection in the evening, before sunset. It was still washed out, but nice to be able to use it with some sunlight still.
The bad... Despite the flat base, the size of the base is not very large and thus still unstable in anything other than a slight breeze. The screen itself does not attach very tightly to the stand. And, because it's meant for front or rear projection, there are no rear crossbars. While this is normally fine, when windy, the screen curves in, distorting the image and becoming a wind sail. I had to put a table behind it to stabilize the poles even with 10lb weights on each stand.
The project screen also comes with a carrying bag. However, the bag is really poor quality, with the stitching ripping immediately when I lifted it from a single strap.
Overall, if you plan on using this indoors or in areas with minimal wind, I'd highly recommend it. However, if you bought this thinking it'd be more stable in the wind, you'll be disappointed.
