These are the exact same models used by car repair shops. We used to have to go to a NAPA or O'Reilly store to find out what the light on our dash or the error light meant. They plugged in their car and told us what it meant. Now we can do it ourselves. Saves a lot of time. The biggest advantage of buying it yourself is that if you can make small corrections yourself, you can keep plugging the machine back into the computer to check if the error code is gone or not, instead of constantly driving back and forth. who has a car.
