Espresso Coffee Grinder Single Dose Hopper with Silicone Bellow Air Blower Blaster for Blow Out Residual Coffee Grinds Compatible for Mazzer Niche Zero Mahlkonig EK43 Fiorenzato Grinder

Perfect replacement for the DF64 hopper. Identical size to the original, but made of silicone instead of rubber so may last a bit longer. The metal lid doesn't fit great, and the logo on the lid is a little chintzy. Would be classier if it were just black. But I'll take it for the fit.

This seems to be well made, works well and fits with my Baratza Encore ESP (I have the OEM single dose hopper). The lid does fit a bit tight so it can be cumbersome to open after use, but it isn't a hindrance. The bellows does its job of removing the last .2-.5 grams of coffee retained in the grinder. Before I used to just tap the top of the grinder, which worked okay but would lead to larger retention ever dozen shots or so. A worthwhile upgrade in my opinion.

So I bought this as I was looking for a bellows that would fit my Baratza Single Dose Hopper for my Encore ESP. I had seen a video of someone from the UK who had a similar bellows, and this absolutely does the trick. Just a point to consider, it is just a tad loose (not to the point of falling out). But this actually makes it much easier because when I want to load the hopper I just pull it off. The lid is somewhat frustrating to get off. In terms of performance I was able to get zero retention using this set up. All in all great quality, decent price, super happy about my purchase.

I bought this for my bunnzilla. Things I like a) nice fit b) good looking c) works reasonably well. Things that could be better. a) the top is not very secure, it makes it a bit akward b) it is pretty small and does not move that much air. I have different brand for another grinder much bigger and it seems to work a bit better getting all the fines out. Overall I am happy with it.

I purchased this bellow to lower the retention on my grinder - the Quamar M80. The machine suffers from nearly a 25% retention of grinds based on my testing when attempting to single dose via the hopper. Tests: - With hopper: 18g beans in, 14g grinds out - With bellow: 18g beans in, 17.4g grinds out The build quality is as expected, with a perfect fit against the hopper mechanism. The aluminum cap is feels substantial and seals well against the bellow. Installation just requires removal of the hopper and insertion of the bellow. All in all a great purchase to convert this hopper based machine into a semi-capable single doser.

Product description states that this bellows is compatible with Ceado E37S. Also, a reviewer from a Ceado E37S owner back in 2023 indicates that this bellows "fits perfectly" once the rubber donut in the grinder is removed. I tried it with and without the rubber donut in place and can report that the bellows does not fit either way in my experience. I own a new 2025 Ceado E37S so perhaps there may be a difference in this regard from older machines? That aside, the bellows seems well made but unfortunately I had to return it.

The quality and caps are just fine. The product said it would fit a Mazzer Super Jolly, and the pictures showed the bellows fitting inside the Mazzer collar, but this is too large. It does fit tight around the outside of the collar. I thought about returning it, but in the end, didn’t want to mess with that and made it work. The aluminum and clear plastic caps work just fine. The silicone bellows work well and seem just fine quality wise.

I saw that this model would fit the Quamar 50, but I own the M80. I decided to take a chance not knowing how much difference there was in the feeder throat sizes. It fit like a charm and works great. Machined well and uses a thick silicone material so it should last. Took my 5 pound hopper machine that retained 5+ grams each grind down to 1.

Very happy with this product although the price in AUD is a bit hefty. I am using on my quamar q50 and the bellows function is great, the grinder now retains about .4 of a gram instead of about 3-5g using a conventional hopper. The quality seems good with thick sturdy silicone and a metal lid which fits well. I would recommend this for anyone looking to single dose on their grinder. Of note this would fit any grinder with a 58mm opening for the hopper as that is what mine measures at.
