I got the picopresso and I've used it daily for about a year now. It is more precise and finicky and you need the right grind, but as youtubers have shown and i agree the quality of the espresso and crema is amazing for something so portable. With hot water and pregrind some fine grounds you can bring say to a few day camping and have espresso like a third wave shop quality. I'm in love with this thing. Toss in a ball jar over ice and oat milk and a splash of syrup and i have a inflationary 7 dollar hipster latte for like 50 cents.

These are great for super lightweight pourover (0.64 ounces). The listing says 1.5 cups per use but I think that's ambitious.

For people that don't enjoy espressos, the CLEVER Dripper is a good option[1]. I think this gadget combined with a cheap burr grinder is the best way to get flavourful filter coffee.
