I've read several reviews that mentioned the legs twisting and breaking. It happened to one of us, but it wasn't a deal breaker for us. We rolled up the tarp and attached it to the metal railing with clamps and it was perfect for our needs. The largest clamp was a bit difficult to squeeze with one hand as we held onto the tarp while waiting for the clamp, but not the end of the world. As for the smallest clamps, when I saw them in the box I thought they would break immediately, but we were very happy with the smallest ones. All sizes fit well for what we needed. It was a last minute save when we didn't have time to go to the store and shop. The promised overnight delivery came (not always) and everything went well to prepare for the rain. I would highly recommend them as must-have items for various needs around the home and yard.
