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.
Can it be used for regular brew too or just espresso
It makes espresso but can add water for Americano and has a steam wand for latte and cappuccino making. But pot coffee no not really.
