Review on 🎯 Enhanced Accuracy with Ehdis Digital Tachometer: Non-Contact Reflective Solution by Adam Hardy

Had to replace this tachometer and the second one sent didn't work reliably either. Very dark conditions were required for this touch to give a reading. I had to throw out the crappy batteries on both units and replace them with reliable ones. Maybe this device works well for some people, but I gave up after the second one and found a better spot for it in the trash can. Maybe it works better there.
