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

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.

For years, I had been relying on knocking the grounds chute to release retained grounds. This is much more effective.

Fits the Niche Zero! Works well. Doesn't blow out all the retention, but gets most of it. Love that I can store it in my Niche Zero when not in use.

Silicone bellows that fits perfectly under lid of the Niche Zero; I appreciate that it saves me the counter space when not in use. I do wish the bellows was slightly firmer, but it still does an acceptable job of pushing air through. Wish I could give it a 4.5 vs a 5.

Just right to purge the retention for my Niche not quite Zero.

Perfect fit the Niche zero. I've been using it 2 or 3 times daily for over a year now and it very easy to use. Great for keeping the grind path free of fines. No sign of wear and no issues. Easy to clean with a quick under the faucet.

If you want to pump 5 times and hope that it will work and not bend buy it. Junk IMO Don’t buy

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.

Perfect fit for the niche zero and very surprised how much it actually gets out of, definitely achieves zero retention

Great product works really well 👍

Works as advertised, soft silicone. Perfect fir for niche zero and niche duo. I used on niche zero and now on my niche duo. The opening fits perfectly into the bean hopper opening and the lid closes while being inside the hopper. Recommended.
