Electric Grinder and Roller

The OTTO grinder is the first and only automatic cone filling machine. Whether your material is sticky, moist, dry, or full of stems, it's an electric weed grinder that fills a perfect cone every time at the touch of a button. The Banana bros otto automatic grinder and filler provide a superior smoking experience with a smooth draw and no air pockets, paper runs, or waste. OTTO can also be used to fill bowls, pipes, or any stash container.

When you click the OTTO on is performs the same smooth grinding motion that dumb old human hands do with precision and care every time. Once it detects it has ground up all of your nugs it opens its hatch and shakes to deposit your freshly ground weed in a pre-rolled cone perfectly shaped to your specifications.

The OTTO is a good automatic joint rolling machine because it doesn't replace anyone's job unless you consider your manual grinder a person. It's basically an automatic joint filler attached to a funnel. Amazingly, it works, and you will want to roll way too many joints. Technically it doesn't roll the cones, they got another robot to do that already at the factory. The Banana Bros grinder is worth it if you want all the work of having king-sized joints done for you.
