Which size do I need for my machine?

Match the kit to your portafilter basket diameter: 51mm for many Breville and Delonghi machines, 54mm for Breville 54mm baskets, and 58mm for most E61-style and prosumer machines. Measure the basket's inner diameter if unsure.

Does the constant-pressure tamper really level itself?

The spring-loaded base is designed to stop at a set depth and keep the puck flat, so pressure is applied evenly. It removes the guesswork of hand tamping, but you still need to fill the basket consistently.

What is the needle distributor for?

It stirs the grounds to break up clumps and level the bed before tamping, which helps reduce channeling. Use it in a circular motion, then tap and tamp.

Is the dosing funnel magnetic?

Yes, the funnel is described as magnetic, so it sits on the basket while you dose and helps keep grounds off the counter.

Is this worth it over buying tools separately?

The set bundles the core prep tools at once, which suits beginners. Experienced baristas may prefer a single premium tamper and a separate WDT tool they can clean and replace individually.

How do I clean the tools?

Wipe the tampers and mat with a damp cloth and rinse the funnel. Brush coffee out of the needle distributor after each use and dry it fully to keep the needles straight.
