Outstanding Tool for Automotive Diagnostics – Worth Every Penny
The Power Probe Maestro is an exceptional bit of kit for anyone working on vehicle electrics. It makes testing circuits, fuses, and connections fast and accurate. The functions are clearly laid out and easy to use, even for detailed diagnostic work. The build quality is excellent — solid, reliable, and clearly designed for professional use. The display is bright and easy to read, and the leads feel durable. It gives instant feedback and saves loads of time when tracing faults. This tool has quickly become one of my go-to pieces of equipment in the workshop. If you deal with automotive electrical systems, this is a must-have. Five stars without hesitation.

Poor quality
The first Power Probe I bought stopped working just before it was a year old and had to be replaced. The second one failed shortly after a year. I’ve gone back to using the Power Probe 4, which is much better quality.

A disappointed customer.
I received my circuit tester in excellent time and packaged well. Unfortunately, the colours on the screen are incorrect. I sent it back because there was no option for a replacement and got my money back quick. Tried to buy again and exactly the same thing happened. So I shall try and buy it direct from the manufacturer next time.
