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.
Sort of. You want an even extraction most of all, and while their grinders are probably pretty good, the water coming in doesn’t saturate the grounds evenly and isn’t a consistent temperature.
