"Found a bad fuel pump relay in 30 seconds that had been driving me crazy for weeks. The 10-cycle test caught it sticking after the 4th cycle. Amazing tool."

"I'm a mobile mechanic and this is always in my bag. The live voltage display is great for verifying battery health before you even pull a relay."
