Bad experience with these... I can credit myself partially for them breaking, but I'm not that strong. The company did offer to send me a set to replace the ones I broke, but out of fear of them also breaking, I hired a welder to reinforce all of them.
How they broke? I had 4x4 blocks taped to the feet to make them a little closer to the ones I was using in a competition. While walking with a relatively light weight, I dropped them and the leg twisted off. If you zoom in in the weld, it doesn't look like there was much connection between the pieces.
