The Ancel AD310 OBD II Scanner is a tool for diagnosing car engine issues. It's compatible with a wide range of vehicles, including 1996 and newer US-based models, 2000 EU-based and Asian cars, and newer OBD2 and CAN vehicles. This makes it a versatile choice for most car owners. Functionality-wise, the AD310 can read and clear error codes, display live data, and collect vehicle information, which is beneficial for those who want to understand their car's issues without needing a mechanic.

The scanner's user interface is straightforward, with clearly labeled buttons and a large screen that displays results clearly. It's easy to use, even for those with no car knowledge, and it gets power directly from the car, so no batteries or chargers are needed. The device is sturdy, compact, and lightweight, making it convenient to carry around. However, it does have some drawbacks. While it supports all OBD2 protocols, it's essential to check vehicle compatibility before purchase to avoid any issues. Additionally, the display resolution is relatively low at 128x64, which might be less impressive for those looking for high-definition screens.

The scanner operates on Linux and only supports the English language, which might be limiting for some users. Despite these minor issues, the AD310 is a reliable, efficient, and user-friendly car scanner, suitable for both beginners and experienced users looking for a portable and accurate diagnostic tool.
