Genial

Tolles Tool für den EP-133. Das wertet das Gerät noch ein paar Stufen höher auf mit den vielen Funtionen. Kein Abo, braucht kein Internet, besser geht’s nicht. (So etwas bräuchte ich auch für den OP-XY 😉)
Dankeschön an Brian. 🙏

Works great!

Very happy to not have to have a laptop nearby to make adjustments to the ko2!

Response from developer

Thanks so much!
