Bests & Worsts Reviews from Amazon

Be warned this is not your typical code reader. This one gets into the the technical stuff. A lot I have no idea what I was looking at. I learned to use a few of the functions from uTube videos. I learned enough to find out I had a plugged EGR valve and I have to 02 sensors that are bad. I have the shop manuals for my car and the more I study this instrument the more I like it. The best feature I think is the graphing. Watching the operation of the 02 sensors on the graph mode enabled me to locate the bad sensors in a couple of minutes. If you are willing to take the time and learn how to use this scanner, you'll be glad you bought it. I'm very pleased with my purchase. However when you order this, order a case and the extention ribbon. You will want to protect this little jewel. The extention ribbon allows you to hook up to your automobile computer and be able to sit comfortably in the driver's seat while you are doing the test instead of being hunched under the steering wheel. Great scanner, great price!
