OTC Circuit Testers Editorial Review
The OTC 3631 Heavy-Duty Logic Probe Tester is a reliable and durable tool that works as advertised. It is great for everyday use in a shop setting and provides accurate results when troubleshooting. However, some customers have expressed disappointment as it requires both power and ground to work, unlike other testers that can test for power with just the ground clamp. Overall, it is a useful tool for professionals but may not be suitable for all situations.
