Review on ⚡ ALLOSUN GK5225 Automotive Wire Piercing DC Voltage Circuit Tester with LED & Buzzer Indicator - 6V/12V, 59 Inch Cord - White by Todd Foster

I tried two different types before buying this one. One was at a hardware store and the other at an auto parts store. Neither of them could hold the tiny (car wire from a wire harness) I had to test and they ended up slipping when trying to pierce the wire or I just couldn't get the probe deep enough into the wire. It has a curved area that grips or holds the wire while it's being pierced, which worked fine the first time.
