Pros: I can only confirm previous review: "Very good quality and finishing processing of all parts. Have two O-ring, more compression. Small price for aluminum head" I expected less quality:) When I made desigion to buy it, I thinked that additional finishing will be needed (based on photos - f.e. tears in the holes). But, as you can see on photos from tosha55555, everything is Ok. Really good compression

Cons: I didn't find
