For less than [$] this is a pretty neat little device. There are a few comments I have about it: - The firmware of the ELM327 chip is version 1.4, this means it lacks a few features such as the CRA, CSM, and J1931 JHF/JTM1/JTM5, and the improved MP command, however these are niceties that aren't needed to get the OBD to give all the info you need.
