One of the levers was cracked, preventing it from staying attached to the stand's threaded mechanism. All crocodile clips are of such poor quality that even the slightest pressure will cause them to buckle. I discovered this while trying to adjust the angle and position of the lever and clamp and it crumpled as I got it into position. The clips themselves only have a plastic sleeve, not rubber, which is what I was hoping for. The whole thing is a disappointing purchase and I will be returning it as it is literally rubbish.
