These seem to be well made. Arrived today and was pleased with the color and quality. We were a little skeptical so only ordered one to see how it looked. We need 5 so we'll be ordering more soon. The installation method is ingenious. No drilling or measuring. Just hold them in place and tighten the wing nuts so the flat plate is tight against the inside of the window frame. Might take two people. Easier that way. Then just tighten the nut up against the other side of the bracket. Took longer to take out the old blinds than it did to hang these. That being said they did send the wrong installation instructions, so it took a bit to figure it out, but you don't have to be that smart to figure it out. If the mechanisms hold up these will be a pretty good buy. FYI these do ship direct from China, so it'll take you a couple weeks to get them. What I can't figure out is why they charge sales tax. I doubt seriously China is going to pay sales tax over here. Kinda smell a rat on that.
