Good Upgrade over steel or plastic nice height
Color: Black, Size: 58mm
Pretty good quality. Not a perfectly aligned fit ( interior circle mostly matches up ) Be aware if you have a Stainless Steel portafilter like my premium ECM Synchronika's it will be a weak magnetic fit. Adequate, but not firm by any means. Quite the flare in this collar but the height is good. Much lighter than Steel, more durable than plastic. Half the price of a colored plastic collar with much weaker magnets.

High quality and fits well, I just wish the magnets were a little stronger
Color: White, Size: 51mm
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.
