OTTO is engineered with artificial intelligence to expertly mill instead of grind. Made with Aerospace Engineered Aluminum Milling Plates, OTTO is designed to mill and built to last.

OTTO’s precision-engineered technology automatically adjusts pressure, speed, and direction based on the texture and consistency of your material.

Making a cone takes time, it can be messy, and it doesn't always come out exactly right. With OTTO it is always a perfect cone in seconds. No mess. No waste. No waiting.

"Great product"
"If you are interested in quickly and efficiently grinding flower. . . that's all. Period. Thanks."
"I love it but I lost a piece when I took it apart to clean it & now I can't use it. I just need the x piece that makes it spin on one end is what I lost. I paid to much for it too let it go to waste"
"This allows me to grind and roll in record time. I like to roll an ounce at a time, but the manual grinding and filling takes hours. I can do it in about an hour with the Otto. I highly recommend this to anyone who regularly smokes flower. Cones are nice as well."
"Thankful my niece showed me this. I have had surgery on my hands and suffer with arthritis. Rolling herbs was killing my hands and it was getting hard to do. Thankful that this product does it all for you. Best purchase I’ve made in awhile. I’d like to say my friend is paralyzed on 1 side. She only has use of her right hand. This has really opened doors for her. She is independent now and doesn’t have to wait on me to drive over and roll Her herbs. Thank you for thinking of us old folks. Maybe you should advertise that it helps with folks like us. Thank you"
"Great!"
"Amazing so easy and fast"
"It came with no magnets and have not received a working model yet so I cannot rate it"
"It’s cool. A little unwieldy, in that shake kinda ends up everywhere regardless of how much you put in. I started grinding it over a bowl to collect it all, and that’s been a reasonable fix, but for $150, that seems to be a pretty meh feature. Plus, the grinder alone is like $70, so not sure why all the accouterments added to this (a stand? Papers?) double that price. It’s cool for novelty and definitely convenient, but it doesn’t really seem worth the price."
