"A fast, cheap machine for espresso-like drinks, not a serious hobbyist tool."
The '20 Bar Professional Pump' is a standard vibratory pump. The high pressure rating is mostly for marketing, as real espresso is brewed at 9 bars; this can actually hinder shot quality by forcing water through the coffee too quickly, especially with a non-pressurized basket.
This machine is for someone who wants to press a button for a latte-style drink and values speed and low cost above all else. It's a functional appliance for moving beyond pods without committing to the espresso hobby.
Aspiring home baristas should look elsewhere. The thermoblock heater and panarello-style wand are fundamental limitations that prevent learning proper technique or pulling a truly great shot.
