The coffee maker is quite good. I have tried it with Nespresso capsules and ground coffee, and it's not bad at all. The coffee turns out good with both options. I recommend filling the tank with hot water to speed up the process. Of course, don't let the pressure you may face get to you. It doesn't produce an espresso as such with its crema; it barely produces any foam. But come on, if you use good coffee, the extraction is very correct and the flavor is good. That's what a coffee maker is for, to have a cup of coffee when you don't have a coffee shop nearby.
Amazing portable coffee maker, makes three coffees of up to 60ml each. If the water is cold, it will take six minutes to prepare each coffee. With hot water, it will take seconds, and in this case, dozens of coffees can be prepared. It is less powerful than a corded coffee maker, but it fulfills its function of preparing coffee anywhere. It recharges with the USB cable and takes more than 5 hours to charge. It does not work while charging.
Works really well, this is the second one i've bought, first one has been running for over 6 months using everyday, battery lasts a long time for espresso using hot water, and i have used it five times to heat up water without the battery running out yet, very impressed. Good crema on top of the espresso, and very high pressure extraction
