Werkt prima. Onhandige is, dat er geen optie bij zit om de code te kopiëren. En omdat het schermpje over je scherm opent waar je code moet invoeren, is enige optie de code te selecteren, rechtermuisknop en dan code kopiëren. Op zich prima, als er daardoor niet een spatie in het midden van de code wordt meegenomen (code bestaat uit 2x 3 cijfers). Voordat ik dat doorhad...Nu moet ik die spatie iedere keer verwijderen na het plakken. Room for improvement!
