Caffewerks 58mm Stainless Steel Backflush Disc

Honestly didn't expect much from a plain metal disc, but this thing is perfectly machined and drops into the basket without any wobble. My backflush routine actually feels solid now instead of the plastic puck slipping around.

The solid stainless build feels way more durable than the plastic plugs I've used before, and it sits perfectly flush in the basket. My backflushing routine takes half the time now since I don't have to fiddle with rubber stoppers that always shift around.

Switched to this disc for my weekly machine cleaning and the stainless steel construction feels much sturdier than the plastic plug I used before. It creates a perfect seal in the portafilter every time without any fuss.
