This is a great stand for the price, and what I've been using for a while. I had to hot-glue the feet in like others have stated in Amazon reviews. The only other significant point against is that I've found the finish scratches easily. But for the price, it's extremely stable. I put a saddlebag weight on it when running full height just in case.
Last week I borrowed some mics and ran 6 channels all at the top of the stand - by far the most weight and dollar value I have ever put on it - Schoeps MK4/MK8 M/S setup w/ CMC bodies, AKG C214s, Church CA-14s, and various mounting hardware which added another few pounds. It held solid. I will say that with that much weight the air cushioning can no longer be trusted - it was a good thing I was holding on to the posts as I released the locking collars during teardown.
