Works great!
I bought this so I could bench test some headlight bulbs and it works perfect! I hate messing with any kind of wiring, but this is just what I needed. I don't know how much I will use it, but it's great to have it and not need it. Worth the purchase!

Great and easy tool
I'm so impressed with this electric tester! It's incredibly easy to use and has saved me so much time and hassle when working on my vehicle projects. The compact design makes it easy to toss in my toolbox and take with me on the go. Whether you're a seasoned electrician or a DIY newbie like me, this tester is a must-have tool. It's taken the guesswork out of my electrical work and given me the confidence to tackle projects I wouldn't have attempted before. Highly recommend this electric tester to anyone who works with vehicles - it's a game-changer!"

Worth it
Pay for what you get! No breaker on the device. Small palm sized. Saves a ton of time. Iโve dropped it and used it in the field a lot, probably 20 days in the field and it still works fine aven though itโs been tossed into tools bags and had stuff piled up on it. Worth every penny
