MiiCoffee 58mm Magnetic Aluminum Dosing Funnel - Espresso Coffee Dosing Ring - with 8 Magnetized Steel Compatible with 58mm Portafilter (Black)

This thing is great, I made a coffee with it as soon as it arrived. I always used a DIY funnel that a made out of a small yogourt container. I never used a 7 needles coffee distruter to even-out the grinds and break up the clumps. This really makes a difference coffee taste stronger and more flavour come through.This funnel design also let you use the tamper while it's still on, it goes right trough. It's light weight, yet sturdy, magnets are the perfect strength. Low profile, but you don't need higher than that. Black fit well with my coffee setup.Another thing worth mentioning, it's a similar design as the more expensive Rocket brand magnetic funnel.

Great dosing funnel that does not go inside the PF but on the outside. So when you are done using WDT there is not a ring in the grounds totally defeating the purpose of the WDT. Magnets are strong. Highly recommend.

This is the overall best dosing funnel I've found so far with good enough magnets, nice and lightweight, and most importantly the inside shape is flush with the basket meaning you get access to all the coffee but none gets stuck on the rim of the basket like some similar looking designs (it also works the same with third generation baskets like the unibasket). If there's one thing I'd change, I'd make it a bit taller as grounds come very close to falling out when distributing with a WDT tool.

The funnel is okay and fits my Rocket portafilter pretty well, but the magnets are very weak and don't hold the funnel on very well. I don't think it's worth the price because of that.

magnets could be a little stronger and the lip around the ring could have a tighter tolerance. using this on ims and decent baskets. works as should despite me being a little nitpicky about improvements.
