Customer Reviews
Customer Review: “Bidirectional OBD II tool that is a must have when you work on your own vehicle. In my case I paired it with THINKTPMS in order to re-program my TPMS sensors during tire rotation, or when the tire shop forgets to re-program the sensors and I can use this to save a trip. When using the THINKCAR scanner, it just works efficiently and saves me time and money.”
Customer Review: “Awesome Bi-directional scan tool and it does everything you would typically overspend for at a dealer.
