### ⭐⭐⭐⭐⭐ Einfach zu bedinen
*by G***N on 19 July 2021*

Das Diagnosegerät funktioniert einfach und unkompliziert. Nach dem Einstecken ins Auto wird das Auto automatisch erkannt und man kann den Fehler auslesen. Auch das Löschen von Fehlern ist möglich ich finde das lohnt sich oft hilft das nämlich schon. XD Der Batterie Tester ist ein schönes feature was dabei ist und funktioniert auch (das Test Ergebnis passte jedenfalls bei mir zu meiner etwas älteren Batterie)
