I haven't rcvd mine back yet from Haze, but my seal was all crooked out-of-box. One wonders how well this seal will hold up over continued rotation switching from bowl to bowl. Personally, I plan on disengaging it from its other half when I need to rotate to avoid wear. Having a dynamic airpath is certainly part and parcel of its design, but wonder if a more active method (manually ejecting protruding nipple anyone
) of closing the airpath will help with consistency. IMO any amount of unwanted air into the path caused by the seal changing shape will result in each unit (each rotation?) behaving differently.
