It looks modern and stylish. The funnel fits my 51mm portafilter very well and does stay put if you're careful inverting it. It's solidly built and feels durable. It greatly helps keep the countertop tidy and allows me to use a large dose before tamping. The one improvement I would ask for is slightly stronger magnets that would hold more securely when I invert it. I tried to place it over the cup of grounds, and the funnel slipped off when I flipped them back over. It kinda works, you just have to be super careful. Better to just pour the grounds into it.

Excellent Funnel

Color: Black, Size: 58mm

Material is high quality. Magnets are strong. Funnel opening is wide. Angle of descent to the portafilter is perfect. Stays on the portafilter very strongly. I am extremely happy with this dosing funnel.

Great for Breville 54mm baskets!

Size: 53.3mm

Well made and a great design. After having tried another big brand distributor that didn’t work well for me, I found this one that works perfectly with Breville 54mm double walled baskets. It offers a minimal adjustment I was needing to evenly distribute without hard pressing before the tamp.

Does Its Job Perfectly

Size: 53.3mm

I’ve had this for years and it’s great. It levels out my grounds perfectly before tamping is very repeatable. I enjoy the ability to adjust the leveling depth to ensure the grounds are perfectly spread regardless of grounds.

Using Normcore Tamper

Size: 53.3mm Flat Base

This tamper is very easy to use and has a perfect weight thanks to the stainless steel build. It evenly tamps the espresso puck, and the 53.3mm fit works flawlessly with my Breville Espresso machine. The puck prep I’m able to achieve has noticeably improved the taste of my espresso. The sleek design is modern, durable, and looks great on my coffee bar.
