Fits well with Ratio 6 and works great. A bit hard to clean but that's what you get with reusable baskets.

*LOVE* it. Very clean cup, fast to drain, *super* easy to clean, top quality.

In awe at the quality of this lad; absolute unit. Precision lasered holes instead of mesh make for a super clean cup w *zero* grounds, only a light amount of fine dust that easily settles to the bottom of your cup and you can just leave in the last tsp; minimal waste. Again; the single, *smooth* surface [vs. all the textured mesh 'mess-masters'] is incredibly easy to clean; you can literally *wipe* all the coffee oils off in a single pass, or just rinse w hot water. Can't recommend it enough. Suffered through a mess-master for years, should have bought this long ago.

Innovative but..

Works and enhances flavour..but bit messy and difficult to clean..not as much a winner as the kone for drip
