Review on 💡 OTC 3631 Logic Probe Tester for Heavy-Duty Applications by Patrick Stowers

This item is accurate, but that's how it should be given its simple design. It does what you would expect but what I don't like is that the LED is very dim making it hard to see. I don't like the bungie cable, I'd rather have it straight, especially since your battery may not be close to what you're testing. The bungee cord will pull the clips off the battery posts if you stretch it a little. Finally, the clamps are tiny. They are rarely connected to batteries and I always have to find a way to connect wires to power and ground.
