If you're smoking cannabis on any sort of regular basis, then you'll probably agree that a good quality weed grinder is one of the best tools that you could keep on hand. It busts apart the toughest nugs with ease and reduces it down to a nice, even fine grind that burns like a dream, and if you get the right one, it will even catch all of your kief and store any extra bud that you want to keep on hand for later. A weed grinder is a stoner's best friend, and that was decided long before introducing a smart version of the beloved tool called the Otto.

The Otto grinder

The Otto weed grinder made by Banana Bros is the very first of its kind because of the compact size that makes it ideal for personal use. You can find larger-scale versions of automatic grinders designed for large scale production, like what you might need to keep a dispensary thoroughly stocked. Still, Otto has the power to shatter the expectations of stoners who seek a more user-friendly experience. This electric grinder doubles as a joint roller, and you don't have to do anything other than load a cone and push a button to make it all work.


Most grinders boast some sort of unique feature, be it a heavy-duty material or a fancy eye-catching design, but the Otto has them beat by a long shot. When you invest in one of these grinders, you'll get the following benefits:

  • 2-year warranty
  • Easy to use
  • 2 in 1 tool
  • Spill-proof funnel
  • Smell proof funnel
  • 2 GMO-free cones
  • USB Charger
  • Cuts grinding time in half
  • An average of 20 full-sized prerolls per charge
  • Compact for easy travel
  • Wireless functionality
  • Separates bud from stems, flower, and seeds with ease


As you can probably imagine, there are very few drawbacks to owning an automatic weed grinder like the Otto, but there are a few things to consider before investing, such as:

  • High cost: $150-$200 on average

  • Limited charge life: This means you must have access to a USB during extended trips away from home.

  • Partial manual functioning: Though this weed grinder is automatic, you do have to be able to hold the device in an upright position while also pressing the button for it to work, a task that might not be possible for the physically disabled.

  • Only compatible with preroll cones: Unless you have some near-professional rolling skills, the only way that you're going to get the joint roller part of the Otto to work is with cones, which can be expensive and difficult to obtain in some areas.

  • High maintenance: Because this is an electric grinder, you will have to be careful to keep it out of the elements and away from things like water, which might compromise the safety and integrity of the USB plug. It also has many moving parts, so frequent cleaning is necessary to avoid part failure and extend the device's life.

  • Consumer feedback

    The Otto grinder made waves in the cannabis industry because for the first time. With a single touch of a button, consumers could have perfectly rolled cones using a device that comes with an incredibly affordable price point compared to large-scale models previously released on the market. It's an excellent tool. Although it might not work for everyone, most who have used it say that it is one of the best weed grinder experiences they've ever had, thanks to the automatic joint roller feature is reliable and consistent.

    Is it worth the investment?

    If you are a lover of bongs or vaping, then the Otto likely isn't for you because an excellent electric grinder can be purchased at a fraction of the price. Still, if you enjoy smoking joints, and have a cone that you'd be comfortable with using on the regular, then it might be just the solution you need. It makes rolling more manageable, which makes getting high more enjoyable all around, and no one can argue with the convenience that Otto has to offer.
