    Very versatile!

    Very nice tool to have. It can read vehicles and equipment!
    We have not had it long, but already seeing a big difference in productivity by troubleshooting our inventory quickly and accurately

    Justin G.
    Worked better than expected

    Not only did this tester work on every truck we have but it also helped diagnose a bad ECM that we have been having trouble with. The support it has on the machine itself is invaluable.

    Jerry (United States)
    Awesome scanner for heavy duty

    I have been using a Snap-on Prolink Ultra for years, but I must say that I prefer the Autel MS909CV. The wireless feature is one of its most valuable attributes. Additionally, it has more capabilities compared to my previous scanner. Overall, it is a great product that I highly recommend.

    Roter M. (United States)

    It works good on my commerical cars, and the diagnostic and information modes are very useful.
