Review on ANNSM Tripod Ball Head With 360° Swivel And Rotation, 3/8 Inch Hot Shoe Adapter For DSLR Cameras, Camera Sliders, Stabilizers, Camera Cages, Microphones, LED Video Lights Monitors & Flashes by Dana Schmidt

Update - just realized that when you actually mount it on a tripod, the base spins freely with no way to keep it from flopping around because the rotation lock doesn't work. No good.Still works okay as a standalone mount sitting on a desk or maybe if your tripod head has a rubber anti-slip kind of gasket.-----------This little flex head is actually surprisingly good for the price. The aluminum parts are machined well and all the joints feel really smooth and nice.However, mine did come assembled backward. It was also missing a screw. The rubber feet on the bottom sit too low to do any good - they can be unscrewed somewhat, but then they're loose and rattle-y. The pan lock screw does absolutely nothing on mine, no matter hard you tighten it - it doesn't lock. It also sits too tall if you try to use the head just flat on a table without a tripod. The 3/8" to 1/4" adapter it comes with also sits too proud of the bottom surface, so if you mount it to a 1/4" -20 tripod you don't really get a stable mount because the actual bottom aluminum surface won't touch.That all said, I took off and turned the arms 180 degrees, replaced the missing screw, took out the pan lock thumbscrew, will probably add extra felt or rubber bumpers on top of the existing too-short ones, and now I have a really nice feeling, well built unit for less than half the price of the name brand that it's copying.
