small table leg, all aluminum (apart the lock button), super light (170 grams) super tough and super stable. Announced support up to two kilos, I tested with my Nikon D5100 + 18 105. It really supports easily and I think he can withstand significantly more (Nikon D7000 with big zoom for example). I had a little doubt about the quality of the patella (the English reviews seen on the net said it is not a true manfrotto) and in the end, it is very pleasant to handle: unclamped very fluid and effortless locking . In addition, when it is released, the ball rotates around itself which is very convenient to place the locking knob in an accessible place (for some space between the tripod and box of an SLR). And once blocked, it does not move at all .. The level of my other ball Manfrotto 494RC2 (in smaller, without adjusting friction). No equilibrium problem with my SLR, even with the extended zoom. Better to get a foot in the oblo for safety, even if it is not indispensable with my SLR. Only downside is very low (the price to pay for stability) so the hot chestnuts portrait mode. It goes with my nikon limit, but only one side and it's a bit of gymnastics. It will not in my opinion with larger SLR (type Nikon D7000 or Canon 60D). And it seems to me that the ball comes apart not just so boring to add an extension tube. By cons, no soucy with a compact for portrait mode. The best part is the price: very cheap for the quality, especially considering dung found in supermarket prices higher. So very convenient for traveling such long exposures. And not carry around a boring !! Last detail: the feet are gray, not silver as the picture
