Snap On has done a good job of offering the bi directional functionality, resets and data parameters typically offered in its other tools into an affordable package. It boots fast, and can auto identify the vehicle. The 17.4 software has come a long way compared to what I have used a few years ago. It offers data and codes for all of the various vehicle modules plus service resets and other bi directional controls. It is priced reasonable, comparative to the other popular competing brands. It intended for those who want the Snap On functionality but do not need WIFI or troubleshooter features.
