"A sub-$200 espresso machine with features that punch above its price, but with engineering compromises to match."
The 'Professional 20-Bar Pressure System' describes the pump's maximum theoretical pressure, not the 9-bar pressure ideal for an espresso shot. Without an internal regulator, this high pressure can easily cause channeling and poor extraction if your coffee grind isn't perfect.
This is for the beginner hobbyist graduating from pods who wants to experiment with the variables of espresso making, like grind, dose, and temperature, without a significant financial outlay. The feature set provides a learning platform, as long as expectations for build quality are realistic.
Anyone seeking consistent, repeatable cafe-quality shots should look elsewhere. The combination of an unregulated high-pressure pump and basic thermoblock will likely frustrate users who aren't willing to constantly adjust variables. For around $100 more, established brands offer much better pressure and thermal control.
