I used to have a Keurig but instead had a refillable filter - instead of pods I just filled the filter with whatever coffee I wanted. Still super convenient, easy for just one cup of coffee, no waste.

I've had issues with several of the reusable cups. Metals ones would let some particulate through, the paper ones would end up tearing.

Plus my experience when I owned a Kurig was not pleasant at the end, with exploding K-Cups.

I've used a plastic one for probably 2 or 3 years now. Came in a pack of two for about $20. Keurig even makes their own now, so it would likely work quite well.

My Keurig even came with the re-fillable cup. But only the 8-ounce size. I had to order the carafe size from a third-party on Amazon.

My mother has MS, and K-cups provide real value to her.

Even ignoring disabled people, the difference between easy and very easy is a huge gulf.

Espresso is IMHO not so convenient to make. You need to prepare every portion separately, filling the filter holder correctly each time etc. This is why I personally switched from a traditional espresso machine to capsules. I still make basic filtered coffee with a normal coffee maker though.

I have a Gaggia Brera Super Automatic which has a bean hopper and grinds the beans fresh for each shot. All you have to do is turn it on and press a button. Every few days you just add more beans, refill the water reservoir and dump out the grounds collection unit. I paid $400 for it 3 years ago and the only maintenance it requires is running decalcifier through it every few months. If you're a regular coffee drinker, I'd say it's a worthwhile investment.

Yes but Keurig isn't really espresso, it is similar to traditional brewed coffee just with some alternative flavor choices.

I guess Keurig is different from the espresso capsule machines. My machine is a locally licensed K-Fee compatible device and there are both brewed coffee and espresso capsules available. The brewed coffee capsules have some kind of mechanism that prevents the usual espresso crema from forming (I suppose by depressurising the water flow).

A stovetop espresso machine takes maybe 30 seconds of active work
