58mm Bottomless Portafilter - Professional Stainless Steel 2 Ears for 58 Gaggia Machines With Walnut Handle & Filter Basket - Not Suitable With E61 Groupheads

Have used this item for about a month now and can't fault it.

First, I am using this pf on a Delonghi Stilosa (EC260) - my overall experience of it is that it is excellent, and provides great and consistent espresso shots.I had one issue when first using it: the puck was only half extracted, some sharp spills and ages to get the coffee out. I then realised that my shower screen was too tight from the last clean, forcing water only on half of the puck.My guess is that the original pressurised basket is a lot more forgiving of this kind of issues, because you have to grind very coarse to get a shot in a decent time - this means that imbalance in the water pressure does not matter much as most of the resistance comes from the bottom of the puck / basket, not the top of the puck.After unscrewing the shower screen a little bit, and making sure the water flowed evenly, the pf worked perfectly well. I suspect, overloading the puck with too much coffee, or a dirty puck screen could create similar issues . Just to be clear: this issue will be the same for ANY bottomless pf vs a pressurised basket and has more to do with the poor design of the Stilosa.I 100% recommend this pf - it feels excellent quality and provides a significant upgrade over the Delonghi pressured basket, only caveat is that you have to be a lot more cautious about how you tinker with your Stilosa, especially after a clean.
