The single knob to tighten all the joints at once is very convenient. The clamp instrument holder works well, much better than the clamps that use a tab on the back of a dial indicator. If you have one of the ubiquitous cases for a dial indicator, base, and point set, this base will fit, but you may need to take a photo once you get it in so you can repeat the performance. I spent an embarrassing half hour trying to figure out how I did it the second time! Here's a photo of how it fits.
