"A low-cost entry to espresso that promises more performance than its hardware can deliver."
The '20-Bar Professional Pump' is a specification meant to impress novice buyers. The machine almost certainly uses a pressurized filter basket which creates a foam that looks like crema, but it doesn't come from a quality extraction which occurs at a much lower, stable pressure of around 9 bars.
This is a machine for someone graduating from coffee pods who wants the ritual of making espresso without a significant financial commitment. It is functional for making milk-based drinks where the nuance of the espresso shot itself is less critical.
Anyone serious about learning to make quality espresso should look elsewhere. The lack of temperature stability and reliance on a pressurized portafilter prevent the control necessary to pull a genuine, balanced shot.
