The most complicated adapters so far are the Mazzer S2 and Mazzer S3 ones which have an extra tube to release the electronics. They will fit the Kony and ZM (MAZ S2) and the Robur, Royal and Major (MAZ S3). The prices are higher than the MK ones, both are CAT C.
This was the first model of the S2/S3 adapters and it was modified to get a more elegant design. 08.08.2018
