At first I thought it felt loose on the grinder and that it would rock or move when using the bellows, but it is great. Feeding is super smooth and consistent. The speed when very low can jam up, but the torque required to achieve this would not be possible with these components. The only thingI would ask for is a timeout function, or at least a light to say it's on. I've left it running overnight once, and I'm sure I'll do it again, with the bellows on you can't see it running and it's so quiet it is easy to forget to switch it off. Great product slow shipping.

I bought this after a lance Hendricks video on slow feeding. It took some adjustment in grind setting to lock this in but once dialed, it’s been a great improvement to my espresso.

Good product

Con esta herramienta puedo echar todos los granos de café sin que se atasque la salida del molinillo, cosa que antes, para evitar esto, debía de echar los granos a mano poco a poco. Tras más de un mes de uso se me habrá atascado unas tres veces, pero el atasco se soluciona en 2 segundos. Muy recomendable.

Great Product. It is easy to use, and I achieved great results with it.

Easy to use, solid quality and a great way to ensure the correct temperature offset for your Espressomachine for a fair price. Very clever design to make it fit with any bottomless filter holder to use in various machines!

Works great, dial in the speed and then easy peasy time save to prep other gear as it slow feeds the beans. Don’t go too slow as it allows a random chance of pinching the beans against another edge, if this happens just bump the speed a little haven’t had to adjust again in weeks. Saves me time everyday.

love the item. Kit Delivered quickly to the UK. No problems assembling - really easy. Works well and consistently delivers the beans at a steady rate.
Really impressed so far.

Nice consistent feed rate into my grinder. Noticed less fine grains on my coffee

Very useful tool to measure temperature of extraction. Easy and convenient to use. I recommend it.

Very well made device. Slow feeding lets me grind significantly finer while maintaining reasonable shot times. Generally good results in the cup.

This single dose hopper and bellow combo is like a spa day for your grinder. It helps flush out coffee grains with the finesse of a barista ninja, turning grinder retention from “ugh” to “ahhh.”

Bonus points for the choice between sleek metal or classy wooden lids; finally, a coffee accessory that looks as good as it works! Single dosing has never felt so satisfying (or so clean). If you love your coffee ritual, this baby is a must-have upgrade!

Works well. Great if you want to play around with slow feeding. However, after all testing, I prefer non-slow feeding of the beans and coarser grind on my grinder.

Works great! Has made noticeable improvement on my DF83V.

Absolutely love the slow feeder pro. When I first started using it had an issue with beans getting jammed. Upon closer inspection it looked like the spinning disk was sitting too proud. Tried pushing it in and it did move a small amount. No issues since, running perfectly.
