Review on Tool Aid 25300 Circuit Detector by Brent Peterson

I have tried many times to use this product but it has not helped me at all. I have lost confidence in this product. It's easy to use, but hasn't found a single bad wire yet. I generally don't use it anymore unless I have time constraints for work. Even then I don't really trust the results as I've had poor results before. I wish there was an electrical buzz when a short is detected rather than just a wide sensor.
