HH OBD Bluetooth adapter isn't in the same class as the scan tool your mechanic uses, but it could very well turn out to be the most valuable player in your toolbox. The downside, in comparison to more expensive scan tools, is that it isn't a standalone device. Like all ELM327 scanners, what it does is provide a connection between your car and a smartphone, tablet, or laptop, which does the actual heavy lifting.
The good news is that most people already own some hardware that's compatible with the HH OBD ELM327 scanner, and if you fall into that category, the device will provide you with on-demand access to the trouble codes and PIDs you need to diagnose all types of problems.
