Rexing OBD2 Scanner - Enhanced Universal Car Code Reader & Diagnostic Tool for All OBDII Cars Since 1996, Read/Clear Engine Fault Codes, Check Smog Readiness, Live Data & Freeze Frame (Black)

This is my first OBD reader. For years, I felt blind about what was happening with my cars—whether a code didn't show up on the dashboard or when a check engine light actually came on. I couldn't be happier with this fantastic tool. As a first-time user, I am really impressed with all the data I can see and understand. Thanks to its simplicity and intuitive user interface, menus navigation, it is user-friendly, and the screen quality is excellent for its 2.8in LCD size. I also really appreciate that it comes with a physical instruction manual instead of forcing you to download a PDF file like other brands do.
I have three cars: a 2013 Subaru Forester, a 2023 Subaru Crosstrek, and a 2020 Kia Sportage. I was eager to try this reader on all three and ended up learning a lot. For example, I discovered the Sportage had been having low voltage issues for quite a while, which I wasn't aware of because there was no dashboard error. It turns out that the LoJack tracking device installed on the vehicle was draining too much power from the battery while the engine was off. I was able to fix this immediately by extending the unit's polling time!
Meanwhile, the Forester reported a 10-degree higher engine temperature than normal, which is something I now know to address by replacing the coolant or checking the fans. I dare say that thanks to the Rexing OBD II, I saved myself from potentially getting stranded on the highway.
This reader is truly plug-and-play. There is no setup required—you just connect it to the car’s OBD port and that’s it. It doesn't require internet access, creating a user account, or the process of gathering data first and then connect to a computer in order to read the codes. You don't have to deal with Bluetooth pairing or installing a smartphone app just to access your data like you do with other units. Thanks to the built-in display, I can see live data. Best of all, it doesn’t need batteries, and I can easily clear check engine light or emission codes without having to disconnect the car battery to clear error codes as I used to do before getting this reader.
I already own a few other Rexing devices (a dashcam and a wireless car adapter), and all of them work great. It is a reputable brand with quality products, and this reader is no exception. The Rexing OBD II is a very affordable, useful tool that you can easily keep in your car or truck to quickly diagnose issues on the fly. I am incredibly pleased with this reader!
