I'm really liking this product so far. Everything is working as advertised. The material is great. No wrinkles. The unit more or less disappears when retracted. And it only takes a moment to pull down, and a moment to put away.Installation is pretty easy, but as there are no instructions, you're on your own. Here's a simple way to do it. Whether installing on a wall or hanging from a ceiling, there are only two hooks (for hanging) and two pre-drilled holes (for mounting on the wall), one at each end, that act to support the unit. Find your first 2x4 under your sheetrock and drill a hole into it. From that point, measure 80 inches. There should be another 2x4 thereabouts waiting for you to drill another hole. If hanging, screw in your ceiling hook or eye hook, add an 'S' hook, then hang one end of the retractable screen from that. Repeat for the other end. Follow the same procedure with screws that will mount the unit on the wall. If you're installing it where there are no supports behind the sheetrock, use drywall anchors.I have a less expensive way to muster such a screen arrangement, but since I don't have the room to have it stand waiting for me to need, I have to disassemble it, and reassemble, ad nauseam. The retractable screen only takes me seconds. Such an improvement. And I think the price is pretty reasonable too. Recommended.
