"A starter machine with a helpful pressure gauge, but its performance claims are inflated."
The '20 Bar Professional Pump' is an inflated number for a basic vibratory pump. It does not improve espresso quality and is mostly for marketing purposes to inexperienced buyers.
This is for someone graduating from coffee pods who wants to start learning the mechanics of espresso. The pressure gauge is a useful training feature rarely found at this low price point.
Anyone serious about espresso as a hobby should save for a machine with better thermal management and a proper steam wand. Experienced users will be frustrated by its limitations.
