I bought one of those OBD2 Bluetooth scanners out of curiosity, paired it with the FIXD app, and I’ve actually kept it in my glovebox ever since. It’s not something I use daily, but during long drives or when a warning light pops up, it’s reassuring to have. Before I bought it, I skimmed through https://fixd.pissedconsumer.com/customer-service.html just to see what real users were saying, it gave me a clearer idea of what to expect.
