I don’t even understand why products like this exist, let alone why they are so popular.

These are less convenient, lower quality, higher cost, have less choice, lead to consuming more microplastic, and generate more pollution

All you should do for coffee is pour hot water on freshly ground and freshly roasted coffee beans.

I can literally buy any coffee, ground any way I want, and brew it with cheaper, safer, and longer lifetime products that use less or no plastic.
