Review on 📊 DROK - 100263 Electronic Counter, LCD Digital Tally Counter 0-99999 Forward People Door Counter Panel 5 Digits Shockproof Retail Traffic Punch Tester Totalizer Gauge with Magnetic Induction Switch by Tyson Mosucka

I attached this to Patrick's (hedgehog) bike to count his activities. Seems to work perfectly! There are no instructions, but you don't need them. Just connect the 2 wires from the Prox switch to the 2 terminals on the back. I had to look closely to see the markers, but one set of terminals is a market RESET and the other is marked COUNT. Connect to the number of screws (obviously). There are no color/polarity issues, it's just a very simple and easy solenoid actuated switch. EDIT for a new personal best! Patrick ran 3.95 miles in one night! Pretty amazing considering his legs are only 3/4 inch long! ;)
