A real time saver in the shop! I am learning woodworking and come from a CNC machining background, so am very familair with this type of instrument. Being able to incorporate this gauge into my workflow has made it a lot easier for me, and I am very happy to work with more accurate cuts. Only drawback has been that it can be slow to react to changes, not terribly so, but noticable. I am never in a hurry as I am just a hobbyist, but some may find it annoying. But for the price I highly recommend this gauge.
