Just got a slow feeder and want to move it between 2 Zernos (Z2 & Z1). The size of the new hopper is just right. The craftsmanship of the hopper and steel cap is also exceptional.

The attention to detail is second to none with these products, and the Step-down basket (and tamper etc.) are a testament to that. Everything from unboxing to using the products, you can immediately see that these products have been designed with love and care by a talented designer. Without hesitation, I would recommend the step down basket above any other step-down basket I own. I can't wait to see what products are released next.

The Lagom Mini 2 is already great with its low retention, but adding this Introvert bellows pushes it to the absolute limit for a true zero-retention workflow. What I love most is that it also acts as a hopper extension—I can now easily single-dose up to 60g of beans in one go! The matte black finish and build quality match the grinder seamlessly, as if it were an original OEM part. Essential upgrade if you want zero retention and larger dose capacity!

Buy it, it is of exceptional quality and in my opinion essential for single dosing workflow. It does add a little height to the grinder as to be expected. I can’t believe Gemilai doesn’t offer a Molight Bellows. I swap between Regular and Decaf all day and retention is negligible. I put 18.1 grams in and I get 18.1 grams out so it helps to achieve zero retention. The stock lid fits perfectly on the Bellows and the Bellows attaches securely to the hopper. It produces a nice solid flush of air when operating. The Bellows has a seam but it appears to strong. I would recommend this Bellows to anyone with a Molight without hesitation.

While this is a 3D printed part, the resultant tool is excellent. The provided needles are just the right length and gauge. I'm appreciative of there being multiple variations for loading the needle pattern, and I've settled on one that works for me. I opted for the wall-mount, and stick it to the side of my Meticulous. I'd love the heft and solidity of a metal one, but this one works so well, I have no need to complain.

So happy to receive and use the Premium Accessories bundle for use with the Beta step-down basket. The dosing ring is very well made and fits perfectly with the basket. While it is not magnetic, there is a silicone ring that adds grip (though honestly mine seems a little light for grip). Minor quibble...

The crown jewel is the self-levelling tamper. It works like a bolt-action rifle. I believe this and a quality WDT tool have completely elevated my puck prep.

The puck screen is very thin, and just what I was looking for. I haven't tried the spring yet, but honestly don't feel a need, as I'm getting such good results already.

I'll start with the build. This is machined from a solid block. No wimpy stamping. The tooling and finish is immaculate. Period. As I've come to use it more, I'm really loving the balance the stepdown basket offers with respect to taste. I even tried some beans that I really wasn't enjoying (on my stock 58mm basket). The taste improved from bad to quite pleasant. With beans I typically enjoy, the taste is fantastic. I'm not sure about the other review stating that they can't get 16g-18g to fit - My typical shot is darker-roasted bean and I'm pulling 17g shots without issue (and with room to spare).

Super easy to set up, perfect fit and excellent for a single double shot serving

I recently purchased my first coffee grinder, a Barazza ESP. I knew that I wanted to do single dose versus storing the beans in the OEM hopper. After lots of searching I happened upon this page. The product met all expectations. Well built and the bellows majorly helps with retention, especially in combination with using the RDT method. I'm very satisfied with this purchase.

Coffee bellows for Niche Zero grinder work extremely well! No more tapping the grinder or having grinds fall out all over the counter. Fits beautifully under the lid as well.

The Alpha step down basket is a high quality bullet design with a pattern of fine holes for extraction. The deep puck in a 49mm size is an alternative to achieve a shot that is similar to a 25gram does in a "20 gram basket. Dosing by depth is the way to achieve the best from the coffee. But, 25 grams is a lot of coffee. Thev49mm achieves this goal with 20-21g. Perfect for a 2.5/1 50g drink.

I am glad i ordered the alpha version of the step down. The results are incredible and so delicious. I use 16grams in and 32grams out, and the step-down basket is so forgiving with the grind size that delicious creamy espresso is out with 2 or 3 grind settings i tried. Amazing to receive all the accessories at no cost, thanks to Andrew for including that. Surprisingly, my order did not come with a dosing ring, but I ordered one from Amazon and have zero complaints with the step-down basket and the construction of the basket.

Thanks Andrew

If you’re a coffee enthusiast who loves experimenting, the Introvert 58 → 49 mm step-down basket is a great upgrade to explore. It keeps your 58 mm setup but gives you a deeper 49 mm puck, meaning more body, balance, and consistency with less channeling and fewer wasted shots.

Just check compatibility and be ready to adjust your grind and dose slightly (usually coarser in my case). Also the taste of my espressos have been on point, so definitely might elevate your espresso game.

Without this step down basket I might not have started doing Slowpresso shots which taste out of this world. Amazing with milk. Really enjoying this basket!

ok, updating review. easy 5stars.

conclusion first:
this was made with passion. im very happy with the product and result. worth every penny. HIGHLY RECOMMENDED.

the nitpicky;
so lets talk about product.
1. VERY well made. fits snug like a glove. print quality is very high. white color is very close.. dont feel the need to airbrushpaint it.
2. the important coffee. this fixes the 078s. really;
- fixes bean feed. they all go through.
- fixes consistent feed. - shot time variance tremendously reduced. this is key. i now pull up to 0.4 to 0.8g difference on same recipe. was avg above 4.0g difference per shot.
- clean workflow. can dump and forget. no fidgeting with covers.
- coffee grounds exit splatters less, more downward. hence cleaner counter. not sure how but i noticed this benefit.

i did taped/printed and modded some stuff myself, but those are nowhere near finetuned as this product.

gears: df64, df83, 1zpressoK, arco, mp64 ls64 bdb.
current: 078s ssp +introvertmod + ecm mechanika max.

for those who read my initial review;
had dome hiccups with shopping custom tax, but introvert helped promptly with immediate action on feedback. something rarely seen nowadays. Kudos for great team.
those who seen the previous review on ship/tax/custom issues should know it has been sorted. buy with confidence.
