Review on Tripod Ball Head Mount With 360 Degree Swivel And Bubble Levels For DSLR Camera, Tripod, Monopod & More! by Nick Palacio

I have a few of these from different makers. This one had the potential to be my favorite but it has two flaws. First the rubber feet don't stick out enough to grip the surface it's sitting on. Second, when you do set it flat the rotation adjustment screw sits too far down that it causes it to rock back and forth because it can't sit flat.Otherwise, attach it to a tripod or slider and it's great!2021-0628 Updated.I just realized that the it will sit flat and will not slide if you adjust the 4 individual feet underneath it.The feet don't look adjustable but they will turn counter clock wise so they can make contact with whatever it's sitting on. Upgrading my rating from 4 star to 5 star.
