The on and off switch could be made better, when coffee maker heats up so does the switch and swells making harderto turn off but once cooled its OK can be turned easily

I immediately noticed that the control knob became difficult to turn as soon as the machine heated up (possibly from internal expansion of the flimsy plastic parts)

And it leaks water and pressure when heated.

Despite this, the coffee it makes will be cold if not consumed shortly thereafter because there is no heating plate like on a regular drip coffeemaker.

It turned over 70% of the water I gave it into super-heated steam that shoots out from the top

Slow heating element, but makes good espresso and will foam milk just fine

First the steamer started to leak while it was heating up, causing it to make weak coffee with a little froth

It loses heat almost immediately

everything works as it is specified in the Amazon page

Works as it should.

I will not recommend this as it makes terrible espresso.

Your espresso will also come out not as strong as it should
