hello and sorry to come back with this topic but the ones opened on it now seem closed. And then today the users of Blow-up must easily be able to announce us the thing.

I'm planning to add a grinder with a hopper to my Niche Zero. I'm thinking of Eureka, either the Mignon Turbo or the Atom (65mm or 75mm burrs, I don't know yet, but I doubt the latter will provide much additional cup quality, and the price isn't the same). I'd like to equip this future machine with the Blow-up system. But does it really work? Is it really effective and does it significantly reduce retention (especially on the Atom with its long spout)? Thank you for your feedback.

I have it. I don't use it. It makes a mess inside the grinder.

I take off the hopper lid and tap on the neck of the grinder with my palm. That works equally as well.

thank you for your information

The usual silicone cup, works with both the Niche Zero and the Eureka Specialita' (with the hopper removed, I use it only when I change beans).
