Hi I'm using his decoders and they are very good. I didn't have the DRIVE-L decoder, but the DRIVE:-M ones They are the same as the DRIVE-L ones with a different board. Marius the owner is a nice man and really helpfull. If you are looking for his switch decoder and you are using the massoth station, you must change a CV. At the moment I don't now wich one, but Marius will tell you.
