Chloe ★★★★★

The fine adjustment knob makes zeroing in on measurements much easier than I expected. Fits securely in my setup with the dovetail grooves holding the indicator firmly.

Harper W. ★★★★★

The steel construction feels solid, and the fine adjustment knob lets me dial in exact positioning without any slip. It holds my test indicator securely in the 3/8" stem hole with no wobble.

Stella ★★★★★

The dovetail grooves grabbed my indicator securely, and the central locking mechanism held position even when I nudged the arm during setup. Only gripe is the fine adjustment is a bit stiff at first, but it loosens up after a few uses.
