### 5/5 — It works!

*2026-02-14*

Installation of the Shot Stopper on my La Marzocco Linea Micra was a breeze. 

I was able to connect and adjust the weight from this app.

The only thing I’d ask for from my initial use would be to see the scale status. My Bookoo connected to the board with no problems, but I could imagine diagnostics being helpful if it didn’t.
