Review on 🎥 Premium Ambient Light Rejecting Fabric for DIY 16:9 130 inch Projection Screen - 70x118 inch EPPE Polymer Material (Grey) with High Contrast Black Backing, 4K Ultra HD Front Projection by David Gill

In the beginning everything was assembled perfectly. Diagonal 100. The 16:9 frame that I built myself takes some effort but is quite doable. 3 months after installation, things aren't going right: 1) you have creases on the edges of the frame support boards (and not just creases, looks like part of the cover has come loose), I think this is due to the material being quite thin and 2) the material expands with a few extra degrees of heat, in heat the screen looks wobbly from lack of tension (it wasn't like that when installed). If I set it back up I would run the temp to 78 or 80 so it doesn't stretch later and make sure the frame doesn't have 90 corners in the corners (sand everything all around, both inside and out) the overall is just fine , not the best material. Update (2/10/2021): So I contacted the seller to inquire about my issues and David at Yandood was kind enough to send me a replacement. This time I followed the instructions in the video they posted where they used the zip ties except I used the tension springs I found at Revain (0.5 x 6 x 26mm) and they on all 4 sides (see photo), I also sanded the bezel to avoid sharp edges and set it to 76°F. The results are excellent! The screen seems to keep its flatness regardless of the temperature!
