Perfect inexpensive option for attaching accessories to my L-bracket, like a phone mount. I like that there is more than 1 type of attachment mount. Holds solid to arca rail. I do wish the knob was a round and knurled, but its good. Also wished it had a 3rd option to set a screw like the DC-12 has. The extra width of the DC-22 helps it sit straight on the rail, the DC-12 can come loose if you dont have it nice and perpendicular to the arca rail. Nothing a little jiggle check cant fix though.
