Review on 🚗 TOPDON AL400 OBD2 Scanner: Check Engine Light Scan Tool with O2 Sensor, Freeze Frame, I/M Readiness, and DTC Lookup - Ultimate Diagnostic Scanner for All OBDII Cars by Joseph Elvis

Very good product. I've bought several Bluetooth devices in the past that connect to your phone. They work fine, but this one works great. Very nice packaging, clean and easy to open. Once it's out of the box, plug it in and play. I like high-end features at a lower price, like the color screen, socket light, easy upgrade feature, and more. The scanner reads stored codes and more. Provides an easy way to search for things with exact code. This unit had many features like checking sensors and more...a great buy for the price.
