I have the leofoto 362c, similar inverted 36/40mm leg setup. The twist locks are upside down to conventional tripods, as the legs are essentially upside down so they're in reverse twist fashion, with thicker section on bottom vs top. Its a decent tripod at the much discounted price. Is it as stable as a RRS 2 section? No I've compared them. It's mainly used for rear support where quick deployment is biggest advantage, and it works well for that. I've used it kneeling to engage targets at 6-700y in matches without issue locked into the anvil.
