The 890 has the same form-factor and functionality as the 875, except that the burrs are the superior "New European" matched burrs that provide exceptional grinding performance. The 890 has the full features of the 835, except in a taller form factor (27" high) to accommodate larger coffee bags. In addition, it has an extra large hopper (3 pounds) that allows you to fill those bags. It features a wider range of grinds, going from very coarse down through a Turkish grind, spanning 11 settings. It also has an automatic shutoff that stops the grinder when the bag is removed. The 890 has an under-tray to catch spills (see photo). The 890 comes in your choice of Black or Red.
Variant: The 890BS
The 890BS is the same as the 890, except it also has an "ETL Sanitation" listing. Note that the 890BS is not available in Red; it only comes in Black.
