After, is broken in operation at my Professionel 2 of the bracket that hold the Pumpenkof and thus water has leaked, I have now decided for the Professionel 3. At first glance the unit make a solid impression. However, the filter baskets act no longer as stable as its predecessor. That the legal ephemeral seals between the baskets are no longer necessary, I think real progress. The connector for the tubes was not very thought of ergonomics: To postpone the hoses, you have to hold the part well, but that will not do, without hurting the process because located anywhere on the housing top plastic guides. What I do not like is the noise: the Professionel 2 has virtually unnoticed, the Professionel 3 buzzing / vibrating slightly and the cabinet amplifies the still.
