OTTO Auto Grinder and Cone Roller by Banana Bros

The OTTO by Banana Bros is an automated joint rolling machine. The world's first, and only, of its kind, the OTTO patented AI milling system analyzes your herb for moisture and density, then automatically adjusts the direction, speed, and pressure of its precision-engineered milling blades to create the perfect grind.

Utilizing a unique milling process, the OTTO cuts your herb one layer at a time, milling it into its expandable chamber. Regular grinders compress and shred your herb, but the OTTO by Banana Bros preserves the quality and structure of your herb of choice. The OTTO feeds the milled material neatly and evenly into the cone, ensuring full delivery of leaf, oil, and kief into your cone roll.
