Used this tool to identify what turned out to be two bad sensors. Purchased replacements, programmed and relearned to the vehicle. I had trouble getting the tool software upgraded after receiving it. I contacted the manufacturer by email and voice message but unfortunately never heard back from them. I was able to get it resolved myself but their customer service has room for improvement. Prior to ordering I contacted Tire Supply Network via chat and the lady I spoke with was able to answer my questions immediately. I’m giving five stars because the tool and sensors work very well.
