This is a Mazzer Super Jolly grinder for espresso coffee. This unit was made by Mazzer, but branded as Rio. I put a Mazzer logo metal plate on the back as pictured.

I’ve made several modifications:

1. It originally had a dosed, I made it doserless by adding a funnel, backplate, and portafilter holder.

2. I added a grind setting measurement label to the grind adjustment collar. I also added an EspressoParts grind adjustment pin to the collar.

3. I removed the imprecise timer installed by the factory and added a momentary switch just above the portafilter holder so that the motor runs while the portafilter presses the switch.

4. I added a static prevention screen to break up clumps coming out of the grinding chamber.

The body has a few scratches. You may want to repaint the body. No dents. With another Mazzer, I had fun refinishing it with spray paint and clear coat. Pretty easy to do. Lasts a good long time.

This machine will last forever! You’ll be glad you bought it!
