This is quite exciting in that it removes plastic waste. I see no reason why different companies can’t make different shape ones to maintain their lock-in. I expect a knock-off market to pop-up, but that exists with plastic pods too. It’s a step in the right direction at least.
3rd party Senseo pads are a godsend; good easy fast coffee with a paper filtered coffee pad that just decomposes. I’m sad that it didn’t work out over Keurig.
I like Carte noir, but their shape is not perfect for my machine.
