The tool looks solid enough, versatile enough and easy to use. The stylus is good enough: Accuracy is fairly consistent in every respect, based on my measurements with a Neiko digital caliper I got +0.003 inches / +0.05mm across all measurements. I would rate it as good enough for a coin probe, although not the most accurate.
