## Customer Reviews

### ⭐⭐⭐⭐⭐ TopDiag P150 Tester
*by C***E on May 19, 2025*

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.
