I’m considering purchasing the Franke A800 coffee machine for my office and wanted to gather some feedback from those who have used it. I’ve heard that it's a high-end, fully automatic espresso machine with a lot of features, including customizable drink options and a user-friendly interface. However, I'm curious about its performance in a busy environment, the ease of maintenance, and whether it's worth the investment for medium-to-large scale use. For anyone who has used it, how’s the quality of the drinks, and have you experienced any issues with reliability over time?
