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.

Le pongo 3 estrellas simplemente porque viene sin caja de uso diario he tenido otras herramientas de este tipo como la autel ps100 y tiene caja por un tercio de el valor de esta, el precio me parece un poco cara pero funciona bastante bien, tienes que tener conocimientos de electrónica para saber usarla correctamente, no me gusta que el idioma de la herramienta está en inglés tendría que tener más idiomas

Il prodotto funziona ma ci sono alcune cose che non sono soddisfatto. sono deluso dall'app ,funziona a "metà" Visto il prezzo mi aspettavo il top lascio 3 stelle più che altro per altri attrezzi prodotti da loro. Mi aspettavo il top visto il prezzo Ora dopo mesi di utilizzo il cicalino fa dei rumori animali,il resto funziona ancora
