Review: Compré este pequeñín para revisar códigos de mis carros en casa. Es muy rápido, y aunque es muy básico, bien vale la pena; pues lo podemos transportar en la guantera, o con la herramienta. También resulta una gran ayuda si te gusta hacer mecánica en casa, o para dar seguimiento a fallas intermitentes o recurrentes. Todo muy bien. Sin embargo, no pude encontrar la marca Autel por ningún lado ni en el producto, ni el empaque.
Review: Easy to use. Worked great in my 2018 gmc. Picked up the issue even when the dealership missed it or maybe they just over looked it. Now I can tell them what to fix.
