Baristapro 18g Nanotech Precision Portafilter Basket

I counted the holes out of curiosity and yes, 661 exactly—and the electropolished finish makes the coffee flow through with zero channeling. The deburred edges are a nice touch too, but honestly the consistency shot after shot is what sold me.

I was skeptical about the 661 holes making a difference, but the extraction is noticeably more balanced from first to last drop. The electropolished finish also wipes clean effortlessly, which is a nice bonus.

The deburred edges on this basket make seating it in the portafilter effortless, and those 661 tiny holes really do produce a noticeably more even extraction. I've been getting consistently beautiful, syrupy shots with zero channeling since I switched.
