Acratech i'm at ball head is a solid device and of the ball heads I've tried this is by far the best in terms of design, build quality, durability and most importantly Handling. Most tripod heads, like the Manfrotto heads, are made from die-cast metal, but this one is CNC-machined from aluminum, giving it more of an aerospace quality. I like the black matte finish and the location of the cocking knob.
