The Ascaso Steel Duo is a dual thermoblock espresso machine with zero verifiable owner data in the wild, which is itself the verdict. Without real-world reports on thermoblock longevity, shot consistency, or whether the steam wand can texture milk without a five-minute cooldown, you're buying blind. At this price point, that's a gamble most home baristas shouldn't take. Stick to machines with a proven track record until actual owners start talking.
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.
