Nothing like good old coffee makers

Nothing like good old coffee machines, piston size is too small, and even if the coffee is not ground it goes back end between the piston and the verre.J'en have an ancient works it perfectly and in which the more the filter is removable for easy disassembly, which is not the case on this one I wanted to buy another dwelling. It's also three weeks I expect the return form the Anglo-Saxon supplier to be able to return and get a refund.
THEREFORE MUST FLEE
