The Enea on Demand by Casadio is a great entry-level grinder, with its 64 mm flat burrs and 2.65 lbs. bean hopper. The grinding process is all handled through the push button display. This allows for complete control over how fine or coarse you want your coffee to be thereby affecting the time of your shots. Additionally, removing the bean hopper is easy and safe, as the grinder automatically shuts off when you unscrew the micro-switch.
