I've been meaning to post this for a while now, but didn't have sufficient evidence from my own experience. I bought the Benro KS-2 several months ago kind of by mistake. I had forgotten the name "Induro" which got good reviews on another site, and went with "Benro" because of the final "o" I guess. I could blame a misguided impulsive certainty, or I may possibly be stupid, or because it was being offered by KEH for $94 which I thought was too tempting to resist.
Well... a couple of days later I got the thing, and checked it out online only to discover the scathing review that's linked to above.
DO NOT HEED ALL THE NEGATIVE REVIEWS YOU READ!! This head may be made of petrified chewing gum for all I really know, but it's been a joy to use. From the negative review, I learned what not to do with it, and so I've had no problems with moderate weight MF and LF cameras and lenses that don't approximate the weight and stress of a medium caliber howitzer. I am not trying to challenge the very certainly overstated claims of the maker that it will support a ballistic missile, but with loads not in excess of a dozen pounds or so, the thing has done beautifully. For the price I paid, I'm about over the top happy with this ball head, and for that price plus shipping (all told, the cost of two and a half dinners out with my wife and son) I have absolutely no regrets, and would buy another if it were offered in the same condition (indistinguishable from new), and for a similar price. So there!
