Reviewers are split on the Ascaso Steel Duo PID: while many praise its temperature stability and steam power for latte art, others report frustrating build quality issues and inconsistent shot volumes. Its dual thermoblock design heats up quickly and offers good clearance, making it a convenient choice for home baristas, especially for milk drinks. However, the programmable volumetric controls are often unreliable, and some owners encounter serious defects like fried relays or internal errors, raising concerns about long-term durability.
