As some of us know, the wide temp. swings permitted by the cheesy button thermostats installed on most espresso machines in the under $1000 class are the cause of poor quality shots. You need no longer tolerate this. For under $200 on most machines we can solve this problem, permanently! And give YOU full control over brew temp., accurate to +/- 1 degree C, 2 degrees F. And now you can leave your machine ON all day without fear of boiler dry out.
