Pretty simple and no-frills OBD2 scanner. I tried this on a 2013 Subaru Outback (see my video for a demo) and a 2019 Ford F150. This is a plug and play device. I was able to code on my Subaru, detect it and then clean it. It doesn't have many whistles and bells, but it will allow the typical hobbyist to examine pop-up codes and maybe determine if it's something smaller (like a leaking gas cap). If it's something more serious that requires a trip to the mechanic, at least you can have a better idea of what's wrong with your car. Inexpensive and compact enough to put in your car.
