You Get What You Pay For - and you don't pay much for this...
The titile says it pretty well. These are cheap and that's what you get. It has all the right parts and adjustments, and each part, joint, thread and fitting is VERY flimsy.
I bought two of these to have for backups and for extra stands when my band has horn players, etc. and they will be just fine for that, but these won't survive a single month of road use, so don't ask it of them.
My K&M is still solid after 12 years of 3-gigs-a-week use. If you want something you can depend on, you can't do any better than those. You can even tell just by the weight (or lack therof) that these stands are no pro-grade.
