Groz 03537 Electronic Edge Finder with Audible Alarm - Precision Tool for CNC Milling, Lathe & Drilling Machines | Workshop & Industrial Use

Cheap junk made in India. The red lenses for the light were falling out, battery was dead. I replaced the battery and it still didn't work. I took out the LED/buzzer assembly, and it was the cheapest looking piece of electronics I've ever seen from a commercial supplier. An LED, resistor and buzzer badly soldered together with some electrical tape holding it all in place. Even if this unit had worked, I can only guess that once the electrical tape turned to goo it would all be over.Not worth it at any price.
