Summary: A ballhead unit is an indespensable item when mounting a camera on a tripod, Gorillapod or a monopod, particularily one that allows the camera to be rotated 90 degrees to the horizontal or vertical position. The Slik version is well built and positively locks the camera into position.
Summary: I was looking for a tripod head for my Gorillapod. I didn't research much and i think this one was one of the suggstions in some B&H kits. Perfect for any compact camera and lightweight DSLRs. My only hesitation would be if the plate is too small for a bigger DSLR. It does the job and it has a secure lock.
Summary: Good value for the price. Attached easily to my Slik Pro 330 tripod. Does everything I need in a ballhead. In windy conditions I would probably need a heavier and more sturdy tripod system. I normally use a monopod in my wildlife and nature photography.
