To expand on that (it was getting late...)
I had a stand develop the well known "sticky handle" syndrome. Contacted them - not interested. It didn't really bother me at the time, as that particular stand hardly ever gets moved/touched/adjusted.
A couple of weeks ago, I had cause to move it. Picked it up, and the handle/clamp mechanism fell apart.
I have a couple of other Hercules stands which are fine, but I shan't be buying any more.
