How To

For an extremely easy to use grinder and automatically roller, look no further than the Banana Bros. OTTO Grinder. It is an all-in-one machine that uses cutting-edge technology to provide the best grind and roll combination in the industry!

To use, simply open the dry herb chamber using the button on the side of the Grinder. Fill with your botanicals and snap the chamber shut. Next, load the fresh seal cone tube with a cone and attach it to the grinder.

Finally, hold the power button and press it again once when it lights up. In almost no time you have the perfect ground flower cone. You can even use this product with tobacco leaves and other botanicals. It works exactly the same way as with herbs.

If you just want to use the grinding feature, do not attach the cone tube. Instead, attach the O Funnel to the grinder and get your storage container ready. Press the power button and get ready for perfectly ground materials of all sorts!

Build Quality 

The grinding apparatus mimics a human hand, so you get an evenly grounded herb every time! Even better than a human, this technology changes how it grinds based on the size of your flowers. This takes all of the guesswork out of finding and buying the perfect grinder!

In terms of the quality of the cones, the Banana Bros. brand are translucent, unbleached, and fit perfectly into the OTTO grinder tube. They even come with filters so you don’t have to deal with roaches. In addition, the whole thing burns evenly, no matter what materials you use inside of it.

The Otto is well put together and made of high-quality materials that work together smoothly and quickly. The design is spill-proof, and the fresh seal cone tube attaches using the power of magnets. Even if you drop the OTTO, the connection won’t break.

This Banana Bros. device gets an A+ for build quality!

Convenience 

If you want the perfect joint every time with no effort, you will love this product! The Banana Bros. OTTO Grinder is extremely convenient to use. There is only 1 button, so there is almost no way you can mess this up. Say goodbye to wasted materials with the included spill-proof O-Funnel!

Even traveling with this 1.28-pound unit is convenient. The measurements are a small 2.5 inches by 7 inches by 11.5 inches. OTTO fits perfectly into luggage or backpacks and is odor-proof to avoid detection. You can charge this portable device at any USB port.

The only thing not convenient about the OTTO Grinder is the need to clean it frequently. After 3 uses you should do a quick clean, and after 10 uses you should do a deep clean. This is due to how quickly the grinding chamber gets mucked up from the botanical resin.
