Works great

This is a great customer service oriented company. I had some questions about my purchase and they replied very quickly. The P150 itself looks to be a very durable, accurate, and handy tool to have. Not to mention very reasonably priced. I used it immediately to test powers and grounds on a ABS module showing a B1342-EO DTC. This showed to me the module is bad. Great company, price, and tool with fast delivery.

The probe is pretty great it let you know if the alternator is charging can do injector testing shows the exact voltage shows if the voltage is dropping it's pretty good can power up fuses the basic but yeah for cars if you're working on car is that pretty good thing to get
