Accurate Depth Gauge
We use them for adjusting elevator disc brakes. They work very well. Very east to use, and accurate. Ordered two already, and ordering a couple more now.

Accurate and affordable
Machinist by trade and tired of changing rods on the conventional depth mics , decided to try these and can’t recommend them enough , accuracy is right there with my brown and sharp and starrett depth mics without the hassle of changing rods and Calibrating , no longer have to setup 1-4 depth mics and carry across the shop to run jobs, cheaper than a single set of traditional depth mics and like most you’d need several traditional styles to do a single job or constantly change rods and calibrate which kills production

Perfect for checking dado accuracy on wood
depth gage seems well built and solid. Storage case is cheap, but it's lined with foam so it does it's job at protecting it. For me and my use case, its way more accurate than using standard calipers or dimensional set-up blocks at measuring depths all along the dado cuts.
