At a glance
Banana Bros. is a Los Angeles cannabis-accessory company best known for OTTO, a rechargeable device that mills dry herb and feeds it directly into a paper cone. Founded in 2017 by inventor and CEO Dave Richmond and director of innovation Manny Montano, the brand focuses on automating one narrow, messy preparation task rather than selling cannabis.
Founders and invention
Richmond and Montano were experienced herb users and consumer-product developers who saw that grinding and filling a cone remained inconsistent for people who could not or did not want to hand-roll. Richmond has described a long career in direct-response products and invention; OTTO became the pair’s answer to that specific friction.
The founders redesigned the device even after initial tooling had begun because the first form did not meet their standard, accepting added cost and delay. Banana Bros. launched around the patented combination of adaptive milling and a magnetic cone holder, then built its accessory catalog around that core machine.
How OTTO works
The user loads dry herb into the upper milling chamber and places a paper cone in the magnetic O-Tube below. Internal sensing adjusts blade direction, speed and pressure as material resistance changes, then the milled herb drops into the cone. Banana Bros. markets this as “AI” or smart milling; practically, it is an automated sensor-and-control system, not a generative artificial-intelligence product.
The device mills rather than using a conventional toothed grinder action. It supports standard King and Shorty cones with the supplied components. Performance still depends on material moisture, cleanliness, cone placement and maintenance, so “perfect every time” remains advertising rather than a guarantee.
Current products and accessories
The core product is the OG OTTO, currently sold with the grinder, O-Tube, cone starter pack, measuring cup, adapter base, Fresh Seal Tube, Snap Cap, cleaning/tamping tool and charging cable. Some current units and manuals use Micro-USB rather than USB-C, an important generation-specific detail.
The line also includes a Shine × Banana Bros. metallic-gold OTTO packaged with gold cones, replacement parts, carrying cases and compatible raw-fiber cone packs. The official store and authorized accessory retailers sell the hardware; Banana Bros. does not sell flower.
Patent, warranty and accessibility
Banana Bros. describes OTTO as patent-protected, and the OTTO trademark is federally registered to Banana Bros., LLC. The published manual provides a one-year limited warranty for the original purchaser under normal household use.
The automatic workflow can reduce fine-motor work for people who find manual grinding or rolling difficult. That is a design and accessibility benefit, not a medical-device claim. The machine does not measure cannabis potency or make consumption safer.
Press and recognition
The brand’s press archive records product coverage from CNET, GQ, Gear Patrol, Cool Material and specialty outlets. Recent features placed OTTO on electric-grinder lists or called it a luxury grinder. These are editorial reviews and rankings, not engineering certifications or consumer-safety approvals.
Where to buy and support
OTTO and accessories are sold directly online and through authorized headshops and accessory retailers. The official store currently advertises U.S. ground shipping and maintains instructions and replacement components. Buyers should verify voltage, charging generation, cone compatibility and warranty eligibility before purchasing used or third-party stock.
The High Rise read
Banana Bros. is a hardware story with a clear inventor, launch year and job to be done. The robust page should explain the founders, mechanics, kit, compatibility, warranty and limitations—not call OTTO an “AI grinder” and stop there. Its strongest case is convenience and repeatability for cone users; its tradeoffs are price, cleaning, battery dependence and a very specific workflow.
Availability and licensing
Availability changes by market and date. Use the official site or store locator for current inventory, and for regulated cannabis products confirm the licensed seller and manufacturer in the jurisdiction where the item is sold.
