Banana Bros. OTTO Weed Grinder Background

The Banana Bros. OTTO weed grinder (Amazon) is easily the best automatic grinder available and one of the best grinders period. It’s larger than any other auto grinders you’ve seen, but the trade-off is that it provides a better grind than even the Best Weed Grinders.

The OTTO grinder is versatile enough to work with tobacco and with a wide variety of herbs, but we all know there’s only one herb you’re thinking about. It works great with the dry kind of herb if you’re into smoking it, but what if you’re into vaping it? Does this grinder work for vaporizers too? Keep reading my Banana Bros.

Banana Bros. OTTO Weed Grinder Design

The OTTO is pretty big for an automatic grinder, but it has a sleek, minimalist design and a host of features that you won’t find anywhere else. The standout feature is that it grinds the herb directly into the joint, no pre-rolling necessary. It basically brings your prep time down to zero.

The other standout feature is the automatic grind function. The OTTO will adjust the grind based on the material placed inside it. No need for any adjustment or calibration, just press the single power button.

The other-other standout feature is how simple the whole device is. The grinder itself is only comprised of two parts and the cone tube or O funnel snaps onto it easily. That’s all there is to it. It makes cleaning and maintenance a simple affair. Overall, the OTTO grinder is an intuitive, cool looking, high-tech device.

Banana Bros. OTTO Grinder Cones

The grinder cones included with the OTTO are unbleached, translucent, well designed, and fit into the cone tube perfectly. They burn slowly and cleanly with good airflow and pure flavor.

There’s no need to worry about canoeing since they burn evenly. Even though we prefer you vape your weed rather than smoke it, these cones are a good choice if you decide to do the latter.

They come in a cardboard box and have quality filters so you can use up all the weed in the joint without a roach left over. Once you run out, you can order a pack of 100 OTTO grinder cone replacements for $145 Amazon.

How to Use the Banana Bros. OTTO Weed Grinder

Your first step should be to use the measuring cup to determine exactly how much herb you need. It can measure a joint’s worth if that’s what you need, but if you’re going to be using your herb in other ways, then adjust the amount accordingly.

With Pre-rolled cones

  1. Open up the OTTO to expose the grinding chamber.
  2. Place your herb into the chamber and close the OTTO.
  3. Place a cone into the cone tube and attach the tube to the OTTO.
  4. Press the power button to start the grinding process.
  5. Once grinding is complete, separate the cone tube from the OTTO and remove the filled cone.

For Regular Grinding

  1. Open up the OTTO to expose the grinding chamber.
  2. Place your herb into the chamber and close the OTTO.
  3. Attach the O funnel to the grinder and press the power button.
  4. Once grinding is complete, dispense the weed into the receptacle of your choice.

Banana Bros. OTTO Weed Grinder Performance

The OTTO produces a perfect grind every time without the need to make any adjustments or tune any settings. Even better is that it grinds up the majority of the herb with very little left over. That makes it one of the most efficient auto grinders as well as one of the most advanced.

The OTTO herb grinder is just as good for vapers. Since the OTTO grinds your herb so well, you’ll end up doing more with less of it. That’s because the finer the grind, the more surface area of the herb chamber is covered by your weed. No matter what kind of dry herb vape you have or what kind of weed you use, the OTTO will have them in perfect vaping harmony.

The only slight downside is that transferring the herb to the vape isn’t as straightforward as transferring it to the cone. The large mouth of the O funnel makes transferring the herb directly to the vape’s herb chamber fairly tricky. You need to empty the ground herb somewhere else and then transfer it to the vaporizer’s herb chamber. That’s one extra step compared to the cones but it’s not a big step and it’s definitely worth it once you experience how much better your weed gets vaped.

The OTTO shows your weed and vaporizer lots of TLC so you need to show it some in return because it needs to be cleaned regularly. A quick clean every 2 to 3 uses and a more thorough cleaning every 10 to 12 uses is necessary. That’s because resin from the herb can stick in the chamber. A perfect grind for some occasional cleaning? I think that’s a pretty good tradeoff.
