Free, in-depth upgrade guides for home espresso machines - Gaggia Classic, Rancilio Silvia, Lelit Anna, Flair 58 and more.

Every guide is written, photographed, and tested on real machines: PID installs, pressure mods, full teardowns and rebuilds. No affiliate fluff - if a part isn't worth it, we say so.

If a guide saved you a multimeter session or a wrong part order, this is a way to say thanks. Coffees fund parts for the next teardown, hosting, and the time it takes to photograph every step properly.
