PID Retrofit KIT for Gaggia Classic Pro & Classic & Home
[KIT-GG]

Received the product today. Directions were spot on, took me about 1 hour to do the work. I have a Gaggia Classic from around 1999. The temp set exactly to 216 degrees like the pid was programmed for. Made 1 cup of expresso that came out fairly well. Now all I need is a mazzer grinder and I am in business. It is nice to know exactly what temp the boiler is at before you pull a shot.
