Beautiful piece of engineering to make espresso. Very versatile because it doesn't have any chip to control the brew process. This method can last many years if you clean it very well. I recommend not leave drops of water inside the machine and avoid soaps because they can make it oxidative. I tested and I prepared good espressos. Please, consider variables such as pressing the coffee, extraction time, fire and amount of coffee ☕ to improve your espresso. I recommend this beautiful ❤️ machine. It is heavy and we'll built. I did an unboxing of 9barista on YouTube in Bogotá, Colombia.
