Any difference with performance & cup removal ?
Just curious , too late now - I bought it !!!

I bought mine used, he said it was about 2 years old then, so about 2.5 to 3 years old now.I am guessing I have the newest Generation.
Hard to compare the 180 and 250. The 250 is a beast compared to the mini 180.
I liked being able to just lift the cup off for the ease of it. Not sure if it would make a difference to performance though. One would think it would be difficult to remove any of the threaded parts without it being obvious, just as adding seals etc would be seen to be done by a person, not the manufacturer. So probably safe to say it was designed to work like that

Just as Sphelps said. It was probably a design change
