Review on All-Sun Electric Circuit Tester: Advanced Automotive Electrical System Diagnostic Tool with Probe Hook by Roberto Manzer

I only rate products that I really like. Every mechanic should have this tool set. This tool allows you to quickly determine if the correct voltage (or ground) is present or if a load is connected to the circuit, and then immediately apply the correct voltage or ground. No more deceptive false voltages or resistances. The cord is about 16 feet long so you can use it anywhere in your car! Compared to the expensive brand P, this price is amazing.
