Had high hopes for these -- reviewers liked them, and they looked handsome out of the box. But the enjoyment thinned out quickly. I bought two pairs. In the first, I couldn't tighten one pole's height adjustment, and found a plastic friction fit inside the height knob had cracked. The other pole of the pair slanted slightly off the vertical, which made the stand look cheap. In the second pair, one pole could not be tightened in the base -- it spun around; the threads didn't engage.These might be pretty good value if you're lucky enough to get a quality pair; I threw the dice and lost twice.
