“The puck filter - aka Muvna P2-Duality Coffee Handle Filter Piece (58.3mm), appears to be exceptionally well made. It looks like a solid disk of metal - the holes are exceptionally small
Unfortunately I realised too late that it will not work in my Rancilio Silvia, as there is a dirty great bolt in the middle of the shower screen which will damage the puck filter when I fit the handle in the group head.
Such is life !”
