Puck preparation · review
A fine steel disc that sits on the puck. It distributes the incoming water and keeps the shower screen clean — the second of which is the reason to buy it.
Where we land on it A cleaning upgrade sold as an extraction upgrade. Still worth it.
Puck screens are marketed on extraction and earn their place on housekeeping, so it is worth separating the two.
On extraction, the effect is small. When the pump starts, water arrives through the shower screen and hits the puck hardest directly beneath the outlets. A screen spreads that first contact across the surface rather than letting it drill. Whether that shows up in the cup is genuinely disputed, and anyone telling you it transforms a shot is selling one.
On cleanliness, the effect is obvious within a week. Without a screen, coffee migrates upward into the shower screen on every shot, and the group needs wiping after each session and dismantling every month. With one, the screen stays visibly clear and the wiping largely stops.
That is a real, daily, non-trivial benefit for about $25, and it is how the product should be sold.
What it does not do is fix channeling. Channeling is caused by density variations inside the bed, and a disc sitting on top cannot reach them. If your shots spray sideways on a bottomless portafilter, buy a WDT tool first and this second.

Slightly, and the evidence is mixed. It spreads the arriving water rather than letting it drill into one point, which helps a little at the very start of the shot. Anyone claiming it transforms a shot is overselling it.
Cleanliness, mostly. It keeps coffee off the shower screen, so the group needs far less wiping and the screen stays clear for longer between deep cleans. That is a real daily benefit even if the cup barely changes.
7.8/ 10
A cleaning upgrade sold as an extraction upgrade. Still worth it.

8 × 0.4 mm (0.016 in) needles · magnetic stand
Eight fine needles you stir through the grounds before tamping. It costs about $25 and fixes more bad shots than any other accessory here — including ones costing twenty times as much.
Best for: Every single person with a non-pressurized basket. There is no exception worth naming.
58 mm (2.28 in) · naked base · walnut handle
Removing the spouts turns an invisible process into a picture. You see channeling happen, which is the only way most people ever learn to stop it.
Best for: Anyone learning espresso who cannot work out why some shots are bad.
58.5 mm (2.30 in) · gravity-driven · depth adjustable
Spins under its own weight to level the bed before tamping, rather than compressing it. Useful if your distribution is poor — and redundant if you already use a WDT tool properly.
Best for: A grinder that clumps badly, where a WDT alone is not producing an even bed.
