Loving it! I use a local-ish roaster's (Capital City Roasters, in Schenectady) espresso blend, and just switched to a ridgeless double basket from the triple. It's amazing being able to rapidly shift temperature, etc., to find where a new bean/blend shines.

Silvia has been great.  Really performing flawlessly.  It took about 2 lbs of beans to get the hang of things, but since that point I have been extremely happy.  I have to thank you again for all the time you spent with me the day of my purchase.  That definitely cut down the angle on the learning curve.  Thanks for being in touch,

Hi... PID seems to be holding steady. I am surprised that the set point is so close to the actual water temp at the group head. Not complaining-I thought there would be more variation. Shots are more consistent for sure... (non-PID discussion removed) ...the PID has performed flawlessly and I am enjoying shots as much, probably more, than ever.

The PID is working great - am getting some really nice shots with that and my Macap. I've even taken to drinking straight shots instead of my usual latte.
