Very happy customer!
I’ve had mine since 2021. It’s worked flawlessly and made me quite literally thousands of dollars! It’s on another level as far as these tools go! The multimeter function saves time and I’ve had no issues with accuracy. In fact it outperforms other basic meters but I’ve yet to compare it with my my Snapon for instance. My Snapon stays in the drawer most of the time so that’s says a lot. I also use their extension cable with the battery connector end for a long cable to which I connect via banana jack many testing accessories. With the cable I have battery + and - wherever I need it around a vehicle. It’s a tremendous time saver and no more wondering if I have a good ground away from the battery. I also have their Break-Out-Box and it’s excellent as well! Whatever they make I have no concerns about buying at this point. I’m rough on my equipment and I expect it to stand up to hard use. Power Probe hasn’t let me down! ... show more

FIRST TOOL TO GRAB FOR ELECTRONIC DIAGNOSTICS
I CAN'T DO WITH OUT THIS TOOL ,,,,,,,, MAKES AUTOMOTIVE ELECTRICAL WORK VERY EASY AND QUICK . I CAN LOOK AT VOLTAGE OR GROUND THAN SEND POWER , GROUND TO KNOW IF MY CIRCUIT IS WORKING AS IT SHOULD . I HAVE EVEN FOUND A WAY TO LOOK AND SEE IF I AM GETTING A PULSE SIGNAL TO SOME AUTOMOTIVE IGNITION COILS . ALSO THERE IS A TEST FUNCTION JUST FOR TESTING FUEL INJECTORS AND MOST OF THE TESTS YOU CAN LOOK AT IN GRAFT FORMAT . JUST WISH THERE WAS A WAY TO USE AN AMP CLAMP WITH IT . ... show more

Does not work as advertised. The app is a failure, and the customer response seems to be also.
I bought the Maestro for the remote features of the app and data logging it provides. So far, it does NONE of this. I bought 100+ dollars of add ons, along with the $380.00 Maestro and it's pretty much useless. For that price point, this product should work. I am a heavy equipment tech and needed this for multiple projects at my job. For a professional, this has been a giant waste of time and money. I am returning all of it and will go with another company that has a complete working product and better customer service. ... show more

Quality
This product is amazing, it's easy to use, it feels like it's quality. It has a lot of features and makes work that could take days turn into minutes. I recommend it and I hope they continue to create quality products like these that make work easier.

Best tool for chasing electrical problems.
This product is a must for chasing down hard to find electrical problems. I have used the first version that came out many years ago and this one does much more. It is like having a multi- meter that only takes one hand to use. I still have not figured out all that this tool can do but so far it does a lot. ... show more
