Great gasket and quick delivery.
Ordered it on Thursday morning, and got it on Saturday morning (with priority shipping). The gasket fit perfectly in the machine.
Pretty quick shipping to Vancouver Canada via post, only took about a week despite border/customs/COVID. Fits perfectly on my machine (Breville Barista Express), no more leaks.
