First contact interesting, pretty serious and product manufacturing. To my Nikon d800 + Pro SLR lens, keeps the foot without any problems unlike GP3 Gorillapod who flinched despite 2 kg of material + a ball. There, nothing to say, works here, here will not move some of the position. More than to try on difficult terrain. Cons: the price for a "little walk without head" and therefore the additional purchase of a ball that will be inevitable for proper use of it.
