I got an OBD Yakry car diagnostic tool to check for problems with my new 'used' car. It was easy to use and I didn't find any codes pointing to the problem. I love that it checks the battery level and has many other features to play around with, but until something happens like the check engine light comes on I can't reproduce or determine how effective it will be in identifying the problem and/or clearing the code (like resetting the oil change light after an oil change: this happened a few times in my last car and I had to go back to have it reset). All in all a good tool to add to your collection and have just in case.
