Construction quality was way below average–the hem of the blinds is excessively wavy, like an intoxicated person cut the fabric with no guidance. The plastic tube inside the hem that weights the blind down bends when you breathe on it–really, a breeze can make the plastic pipe bend. Looked like a higher end synthetic fabric in the pictures, but the actual material looks more like the old plastic-weave folding lawn chairs of the '60s...the sheen is very noticeable in person. On the positive side, while the light is not fully blocked out given the light color of the fabric, my west-facing screened porch is *much* cooler with these down in the afternoon. We ended up hanging some outdoor curtains over the blinds to take away from the cheapness, and they serve their purpose, especially at the price point.
