OBDLink SX Scan Tool
Product Review (submitted on July 11, 2012):
I bought this because my 2006 dodge Durango kept showing the check engine light. Instead of paying for someone else to check the engine codes, I wanted to do it myself. This scanner let me know that the O2 sensor was bad and I was able to fix it myself without needing a mechanic. AWESOME!
