A comprehensive tool. Easy to navigate and setup. Special functions are all that most uswe will need. Unit is quality.

Works just as good as the name brand power probe without the inflated price tag. Saves time by being able to apply direct power.

Haven’t used it enough to go into detail but from what i have seen on videos its durable and from what i have used it its accurate and easy to use i use it to diagnose dc circuits in my vehicles and rv and will speed that up alot

I recommend highly the unit, it is super handy.

Works well , great product.

I will update this review as I learn more about the genius of this tool.

I like this

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.

As a professional automotive technician, a tool such a this is invaluable. I keep one at work and at home. It is an amazing tol to have and use. being able to check power and ground without switching leads, and being able to test small electrical motors and switches quickly is much more convenient.

I got this product because I got a car at work that came in and wouldn’t start so I took the challenge of trying to figure it out and turns out it had a bad ecu I didn’t have a power probe so I ordered this one and as soon as I got it I was able to find the issue along with help.

You can throw your test light away once you learn how to use this.

Perfect for auto electronics

I use it for automotive purposes and it has worked as it should.

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!

I love there product there power probe works great I am very happy with them over all great Customer service.
