Review on ⚡ Astro Pneumatic 7760 Wireless Electrical Circuit Tester by Hamilton Larcony

Awesome tester. Just touch something that serves as ground (a bare metal part of the car) and use the probe to test the power supply. It lights up and beeps. It can be used to pierce wires and reverse test some connectors (the tip is sharp but tapered so its area is limited). For the price it's a must have tool for me.
