Eva S. ★★★★★

Even with the single-knob control, those three pivots lock down tight without any creep, which was my main worry. The base's magnet is surprisingly strong for its compact size and holds my test indicator perfectly steady at an odd angle. A solid upgrade from the cheap plastic bases I've fought with

Miles K. ★★★★★

The magnetic base holds surprisingly well on vertical surfaces, even when I've got the arm fully extended. It saves me time not having to clamp things down awkwardly.

Stella ★★★★★

The single knob makes adjusting this indicator holder so much faster than the old three-knob style I used to fight with. That 70-pound magnetic base is surprisingly strong for such a compact unit, and it holds my dial indicator rock solid on the mill table.
