Banana Bros. OTTO Grinder

Sleek and ergonomic, the OTTO™ by banana bros.™ is the world’s first automatic smart rolling machine. This sleekly designed all-in-one device is able to grind and pack 20-30 joints per charge, automatically and evenly filling premium cones with efficiency. The OTTO grinder transforms bud to joint in mere seconds, delivering perfect rolls every time. Employing their own innovative SMART grinding technologytm, banana bros. equipped the OTTO with a spring-loaded grinder that mimics human hand grinding gestures, ensuring that content is ground to uniform perfection. 20 premium cones feature 100% natural raw fiber and wider lips that allow contents to fill all the way to the tip, ensuring an even burn with a superior draw. Defined by design and efficiency, the OTTO grinder makes rolling easy so you can take it easy.

All-In-One Tool

Engineered for convenience, the OTTO combines the functionality of an electric grinder and automatic joint roller in a single device. No more relying on multiple tools to prepare your dry herb. This travel-friendly powerhouse will grind, fill and roll your bud in one fell swoop–all with the push of a button. The OTTO automatic roller transforms herb into finely prepared joints in just seconds, saving you time and energy every session. You can quickly roll a joint whenever you want, or stock up so you always have a smoke ready. Equipped with patented SMART grinding technology, the OTTO automatically adjusts to the optimal grind for whichever material is loaded.

Premium Cones

The OTTO electric grinder comes with 20 premium cones that are carefully hand rolled for reliable performance. The lip of each cone is sized for seamless filling, and a sturdily rolled design prevents bending and runs to promote optimal burning and airflow. To ensure a higher level of purity, banana bros. uses 100% natural high quality raw fiber. Crafted with care in Bali, each cone is free of GMOs, chlorine and animal products. Expect full flavor, aromas, and effects from each draw with a slow, even burn.

Sleek, Functional Design

The OTTO features a minimalist aesthetic that is both sleek and functional. A single button with an LED backlight gives you easy mastery over your sessions. The chamber features high grade, wear-resistant metal teeth perfectly aligned for shredding dry herb down to fine granules. An o-funnel ensures steady, spill-free loading, while a transparent cone tube allows you to observe your joint as it fills up with bud. Equipped with an airtight seal, the OTTO grinder prevents odors from escaping the tube, ensuring a stealthier experience. A magnetic connection enables swift, snap-on attachment for easy retrieval of your freshly rolled joints, while a USB port enables rapid charging from a variety of power sources. Boasting the ease-of-use of an electric grinder and the efficiency of an automatic joint roller, the OTTO by banana bros. is the ultimate all-in-one tool for connoisseurs.

How To Use OTTO Grinder

Using the OTTO makes preparing and rolling your herb a simple, intuitive experience. Simply load the chamber with dry herb and place a premium cone in the tube. Attach the grinder to the tube using the magnetic connectors located under the device. Hold the power button down to turn the device on, then press it once to begin grinding. This innovative electric grinder will sense changes in the material and make adjustments to ensure the perfect consistency. The cone will then be evenly filled with ground herb. Now just retrieve your pre-rolled joint and get ready to relax.
