Reviewers mostly praise the Gaggia Classic E24 for its solid build and café-quality espresso, especially valuing the brass boiler for better temperature stability and steam power. The machine is described as a great value, with consistent shots and good crema, and the upgraded steam wand is a hit for latte art. However, several users report annoying steam wand drips and leaks, a flimsy drip tray, and a steep learning curve without a PID, making it less user-friendly for beginners.
