Now my Virtuoso+ is complete 🤩

Andrew provides an outstanding, well designed and engineered product in a very timely manner. His communication is equally outstanding. I would highly recommend Introvert!

I use my kalita wave to rdt and shake the beans before loading into the zerno and this makes pouring the beans way easier.

I have a Vario W+(purchased 2024), grinding medium roast for pour over. The hopper feeds all beans and no beans popcorn out of the hopper(20g dose). When using the stock hopper for single dose, a few beans would always hang up on the bottom lip of the hopper. I would then have to brush them down, while grinding.

The bellows is a perfect fit and clears the grinder with two or three puffs. I was retaining .5 to 1.0 grams before using the bellows. I think the item description of 0 to 0.2 grams of retention using the bellows is accurate.

Referencing the photos on the website item page. My hopper is different, having the printing seam lining up with the index mark/narrow lug. Index mark aligns with where the shutoff knob/lever is on the stock hopper. The photo with the hopper filled with beans on a scale is weird. On a Vario, just plan on leaving the hopper installed.

The latest, silicone release of the INTROVERT bellows for the Breville Sage grinder is a big improvement on the previous 3D-printed version. The old-design bellows was already a great addition to the grinder, easily attaching to the hopper and significantly reducing retained grounds and the annoying last few dribbles after you grind. But the material from the 3D printed version was a bit stiff and it looked and felt less than professional. The silicone version blends seamlessly with the design of the grinder so that you'd never know it didn't come stock. I also no longer worry about wearing the material out with excessive use. The silicone has very smooth action and takes a very light touch, so there's no more splattering grounds all over the place. Its a really clever addition to the grinder and I'm very happy I upgraded to it.

I wasn’t sure about the claims made by the author about the efficacy of this tool, and only bought that tool, because it looked more sturdy than my previous no-name WDT tool from Amazon. Boy, was I wrong.

The previous tool was a challenge to evenly distribute the puck. The Introvert one makes WDTing a breeze. The puck becomes even and fluffy with little effort. The resulting coffee is also decent. I regret not buying this sooner.

good good

This little bellows does a great job of helping to clean out the fine dust and residue that remains in the Niche after each grind. I was amazed the first few times I used it to just give a little tap and see a puff of coffee come out of the grind chute. It is now an essential for me.

The material of the bellows looks and feels to be high quality and it feels like it can be compressed and distressed without any damage to the bellows, so I feel like I will be using this particular bellows for multiple years to come.

Really great product, fits well, well designed, perfect for my baratza encore esp for espresso making.
Really good customer service : first order was lost, they sent me a replacement for free. Thank you for everything

We use the 078 daily for cuppings. This is a game changer for us. No need to hold the lid shut like a cobra is going to Strike us while grinding. Install was super easy as well.

Fits perfectly - a nice tool for my wonderful Zerno Z1

The new hopper is a great upgrade for the Sculptor, I would say it is a necessity. A grinder that I already love, Introvert have managed to improve on the small but daily annoying issues due to the original hopper. No more popcorning mess, no more clogging in the chute, no more beans getting trapped on the metal grid above the auger, no more inconsistent shot times. Now, with the option to slow feed beans. I even use the RDT method and give my beans a little spray of water and still no clogging. All these improvements have created a much more consistent grinder from shot to shot. An upgrade every Sculptor owner needs.

Top. I am more than satisfied. No coffee residue remains in the niche Zero. Unfortunately, there were problems with German customs (Zoll). Customer service was totally friendly and the problem was solved quickly and in a friendly manner.

The finish isn't as smooth as the rest of the grinder since it's 3d printed with some minor rough areas and texture, but for the price, the functionality is great. I recommend this grinder add-on highly!

This durable hopper has improved the experience of using my Timemore grinder by leaps and bounds. I love bellows and the bellows work great; the dual-ramp design in the hopper prevents popcorning AND even helps to automatically slow-feed, avoiding jams. I love it and I wish that it came stock on the machine.

PS the installation was very easy and the instructions were clear. Thank you!
