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.
I WFH and only make 1 cup for myself. I don’t want a whole pot.
FWIW I use a regular drip coffee maker and I only ever make a cup per day. I fill my coffee mug and dump it in the reservoir, then use one of the smaller size filters and one scoop of coffee adjusted for the size of my mug. Though typing this out, I’m now thinking of getting a reusable filter basket.
LPT - grind coffee into a French press before bed and add water. Leave it on the counter overnight and in the morning you will have much better coffee.
