This compact semi-automatic delivers decent espresso once you've climbed the learning curve, but the 51mm portafilter is a dead-end street, sparse accessories, no upgrade path, and you're locked into a proprietary ecosystem while standard 58mm machines give you room to grow. The built-in grinder saves counter space but lacks the fine adjustment range for lighter roasts, and occasional reports of machines failing to power on after months of use add real risk to an already compromised value proposition. Buy this only if extreme space constraints force the choice and you're willing to work within its limits; otherwise, a Breville Bambino or similar 58mm machine offers easier onboarding, better long-term flexibility, and stronger resale without the electrical wildcards.
Philips' flagship super-automatic makes genuinely impressive milk drinks, the LatteGo system clicks together in two parts, cleans in seconds, and froths better than most machines twice the price. The touch screen is fast, the drink menu is deep, and when it works, it works well. O-rings fail and leak steam, solenoid valves dump water into the drip tray instead of your cup, and the water tank sensor needs coaxing to register; owners who've had good runs still plan to buy De'Longhi next time. If you want the easiest milk cleanup in the category and don't mind some maintenance quirks, the 5400 delivers; if you want a machine that just runs without the fussing, the enthusiast consensus points elsewhere.
