At first I was doubtful about quality of the item. Reading the reviews didn't give much more confidence. But the price was right and I needed stand for temporary keeping of guitar. But I was very wrong. Although the stand does not look stable, it exceeds all expectations. For me it is the right height, the right angle and right profile for comfortable usage. Now it is my favorite stand. Only thing, the security strap is unusable.
Of course, quality could be better, but actually, for the rice, it's superb. About rotating bottom bracket, I haven't really had any problems with it: it's stable enough and lets you store guitars of different shape.
