I've used almost every available manufacturer's speaker stands(Of this type.) They fall apart in a year or so, and are'nt as stable, specifically, the twist- tighteners. I've used my USS stands for, at, least, 3 years with no degradation,(Quick! Run to an automotive store and get a radiator hoseclamp because the twist- tightener just crumbled in my hand,) what-so-ever.
