PID Retrofit KIT for Rancilio Silvia w/ pre-infusion
[KIT-RSPb]

This is the best kit that you can get!!! Everything is included and the instructions are accurate and easy to follow. It took me 1 1/2hrs to install and it fired up with out issue. Best of all it turns Silvia into a very controlled shot making machine. Had a massive amount of crema first shot out and it did nothing but get better. Highly recommended. A job well done by Auber Instruments!
