Narrowing it down to the code reader that fits your budget AND your needs can be very tough, and that’s why we put together this guide.

In this guide we bring you the BEST OF THE BEST as far as car code readers are concerned, with a product dedicated to high end, mid tier, and low end budgets.

We also have a section on the RepairSolutions2 App, our car code reader and general automotive diagnostics app that walks you through car diagnosis, providing information on what repairs are needed and how much it will cost.
