What is the difference between the original Flow Control Portafilter and the Flow Control 2?

The original Flow Control Portafilter, while still able to craft the same quality espresso as the latter version, did not feature a removable/replaceable spout. This prevented users from more easily cleaning the basket's fixed dispersion screen, and would require complete replacement of the portafilter basket in the event a permanent clog or breakage occurred/occurs.

The Flow Control 2 features a removable/replaceable spout, allowing users to separate for thorough cleaning after use. The Flow Control properties are also solely housed in the removable spout tip, so users can more easily diagnose and remedy build-up. 

All NEOs now ship standard with the Flow Control 2.
