Silicone Retention Bellow Compatible with Niche Zero/Duo Coffee Grinder - Black

This is a must have accessory for your Zerro coffee grinder. It greatly reduces retention of coffee grounds remaining in the unit. It fits perfectly inside the cover and can be stored there when not in use. I highly recommend this product.

Must have for the Niche Zero. One pump is all you need (two max) to get the little retention there is. The best part about the bellow is that it fits in the machine with the lid closed unlike other bellows that are tall and bulky. This thing is small and gets the job done. Nothing more, nothing less.

It’s hard to tell whether this works the way it’s supposed to…but it works. The forced air with each pump doesn’t seem very strong and I think maybe it’s simply the added jostling that’s actually loosing the retention. But my grinder is always clear and clean since getting it. I also lightly mist the beans before adding to the chamber and this also helps reduce retention tremendously.

Very nice low profile silicon bellow for single shot coffee grinders. It fits perfectly inside my Niche Duo grinder - I can leave it in place and close the top dust lid without any problem. The silicon rubber is very compliant and easy to press for a good blow. The top surface is a bit too flexible, so when you press it, use your palm to distribute pressure evenly across the entire top; otherwise, you end up "poking" only a small area and the bellow won't generate enough pressure for a solid blow. I ended up creating a rigid "cap" to sit on top of the bellow (essentially a cup coaster) so no matter how or where I press, the entire top is evenly pressed down. My grinder is now truly "zero-retention" when I use this bellow.

Great product, fits niche duo well. Stay in place while the machine is running and during taps. Works well as intended.

Perfect

This things is a must buy. Prior to finding out about thias bellow I was shaking an bouncing my get the last crumbs of grinds out of the niche. My niche is also the older conical bur model and I thought I did a decent job getting everything out until I used this and BAM maybe a 1/4 of a gram of coffee dust comes flyign out after I thought it was clear or at leats close to it. If grind retention is even remotely on you radar GET THIS.

This is a must have accessory for the Niche grinder - which can have horrible ground retention issues. Using this bellow it clears an additional .2 - .5 grams of grounds after grinding, enough to make a difference in the measured output based on puck size/compaction. This has made my workflow much more reliable and repeatable. I was worried that this might be a pain to use, but you just leave it on the Niche unless you are actively grinding - it is low profile enough to close the lid when not grinding. The design is good, and it seems durable. One star off as mine was deformed - maybe from packaging shipping - and it never bounced back to perfectly round shape, but seems to work fine. Otherwise, a five start product.

Great product works really well 👍

Fits perfectly on top of the niche duo hopper. Prevents the beans bouncing out of the hopper when grinding, and also allows you to plunge air through after to flush out loose grounds. Very simple and does the job well.

Erfüllt seinen Zweck und bläst die letzten Krümel aus der Niche.

Fits well, and works as intended. If I was keeping my Niche Zero, l would be using it every day, but I have replaced it with a shiny new Fellow Ode grinder, which I use every day to make a pot of brew coffee. For large amounts of beans, the Ode grinds faster and more quietly.
