Works very well

These are one of the best tools I’ve ever used. I used it to check if there was any wiring problems in my minivan. It helped me detect the exact location of trouble on wire . It came with so many accessories. I can use it for so much - checking voltage, electricity, battery levels component amper , wiring issues, and much more. It comes with so many different plug types. The wiring is also long . The best part is that it even comes with an extension cord. It even has LED lights at the end, which saved me from using my own flashlight. So convenient.

Great quality fast shipping
Can’t beat the price

This is my first circuit tester, and I’m absolutely amazed by what it can do! Right out of the box, I was impressed with the packaging—it was neatly packed with foam inside the case to prevent any movement or damage during shipping.

One of the first things I noticed was that it comes with a variety of test leads, which adds a lot of versatility. It hooks up easily to a car battery or cigarette lighter outlet for power, and it even includes an extra extension, which is a great bonus.

Using this tool, I was able to test the voltage on any wire I poked, giving me instant and accurate readings. I also checked the voltage levels on different wires, and it helped me pinpoint where open shorts were located. Honestly, I have no idea why I didn’t get one of these sooner—it would have saved me so much time on past projects! Additionally, I tested fuses, and it provided clear voltage readings, making troubleshooting even easier.

Another standout feature is the breaker finder tool. It works surprisingly well—just turn it on, and it emits a static noise to help locate breaks quickly. This makes diagnosing electrical issues much more efficient.

So far, VDIAGTOOL has been great to me. I already own one of their scanners, and now this circuit tester has exceeded my expectations as well. Their products seem to be of really high quality, and I haven’t had any issues so far, which is a huge plus. If you’re on the fence about getting one, I highly recommend it!

Very handy tool

The 30-piece back probe kit is a real game-changer. The variety of angles allows me to effortlessly navigate tight spaces and reach tricky connectors—especially around sensors and injectors. It's a far cry from the old-fashioned hassle of fumbling with wires and stripping insulation.

Good

The 3-year warranty and lifetime technical support were major factors in my purchase, and they do provide great peace of mind. I tested the support with a question before using the product, and I was impressed with how prompt and helpful their response was. Coupled with the 60-day return policy, it makes the purchase feel completely risk-free. Highly recommend.
