Good tool for DIYers and folks who don’t want to waste money at the dealership; not a fancy tablet but gets the job done and explains codes well.

Mark N.

Interface is simple but screen could be bigger; still, I tracked down a failing EVAP valve and reset readiness without a shop visit.

Paul G.

Worked great on my older sedan, displayed freeze frame data and helped me confirm a worn spark plug issue. Saved a lot on diagnostics fees.

Tony S.

Pretty solid gadget overall; wish it had more advanced module coverage but for engine diagnostics it's reliable and has saved me service bills a few times.
