Common questions

Which is better for lattes and cappuccinos, the ECM Classika PID or the Rocket Appartamento?

The Rocket Appartamento. Its heat exchanger (hx) brews and steams at the same time, while the ECM Classika PID uses a single boiler and makes you switch and wait between the shot and the milk. For milk-heavy drinks that wait is the difference you feel every morning.

Is the Rocket Appartamento worth the step up from the ECM Classika PID?

Stepping up from mid-range to prosumer buys you a heat exchanger (hx) instead of a single boiler, pre-infusion. Worth it if you brew milk drinks daily or chase consistency; not if you mostly pull straight espresso. Tiers are price bands — confirm the live price at the retailer before deciding.
