Review on NEXPEAK OBD2 Scanner | Car Diagnostic Tool | Engine Code Reader | Automotive Emissions Analyzer by Jun Merritt

This device works exactly as advertised. If you have a check engine light you can plug it in and it will tell you what's going on. With many codes you can also reset the code, for example you can reset the oil change indicator yourself after changing the oil. For more esoteric faults (like something with an exhaust system) you may still need to take it to a mechanic, but you can google the fault code first and get a good idea of what it means in layman's terms and how much the average repair will cost you feel stronger. This is a great tool for glove box storage.
