I bought it for economy, now I only use 15 grams, but with the smaller amount the larger basket (18-20) didn't work well. With this one, I'm perfectly fine.
Lower quantity, same coffee quality, same enjoyment.

It is exactly the same in specifications as the mama basket that the Gaggia Classic uses. It also has 641 holes with a B68 rim, a flat bottom, and the angle at the end is slightly rounded for easy puck detachment. The holes are slightly larger than the mama basket, so the coffee requires a finer grind. It comfortably holds 17g of coffee + the puck screen. If you don't use a screen, you can fit up to 20g without the coffee touching the shower. A must-buy for the Classic.
