Manufacturer description

The RollBotz RoboKone Filler from Wakit Grinders is a USB-rechargeable electric grinding mill that grinds and dispenses in one step. It skips the usual tooth-and-plate design. A rechargeable motor drives a bead chain that mills material quickly to an even consistency, so you don't have to twist a manual grinder by hand every time. The main feature is the built-in funnel. You can fill sleeves, packets and spice containers straight from the mill, which removes the transfer step where most spills happen. When you're done, recharge the motor with the included micro-USB cable. You never have to…
