You do need to tap the affixed plastic chamber down against the table while your robot grinder hums and whirrs. If you don’t tap it during the grinding process, the ground herb may not descend into the paper cone, and may get stuck in the grinder. But since the plastic is transparent, you’ll be able to tell if this is happening.
Full Disclosure: The Banana Bros. sent me a unit to test out. It fills the included cones perfectly. You twist off the end and it’s all set. The package includes one cylindrical plastic “doob tube,” so you can send a friend off with a perfectly-rolled joint, too.
This is perfect for anyone who struggles to roll joints due to hand tremors, injuries, or other motor function challenges. Or anyone who has cannabis allergies, and doesn’t want to touch marijuana any more than necessary.
The Otto Herb Grinder uses “artificial intelligence” to calibrate the perfect milling pressure for your cannabis, which it grinds directly into a cone. (It comes with unbleached, organic paper cones, which fit perfectly into the transparent lower chamber.)
This Otto Grinder & Joint Roller stands out because it’s a luxurious way to get a tiny, shiny robot to produce a perfect joint for you.
People living with conditions like muscular dystrophy or other mobility issues may like how this grinder is designed for one-handed operation. This battery-powered grinder comes with a funnel attachment, so you can position it directly over a cone, or vaporizer chamber, or bowl, and grind your cannabis directly into your smoking device.
It comes in a wide variety of colors. This would make a great gift for the person with hand or wrist issues, who also loves nifty gadgets.
Want a robot to grind up your bud and turn it into perfectly-rolled joints? Now it can.

Electric grinders are not as popular as manual grinders since they don’t perform as many of the same functions as manual grinders do. Plus they are more high-maintenance since they need to be cleaned and charged regularly. Still, they do have a few advantages over manual grinders:
Herb grinders, aka weed grinders, do exactly as they say, they grind up the herb into a vaporizer-friendly consistency. This is necessary since large nugs won’t fit into most vaporizers and even if they could, they won’t get vaporized completely. Grinders can be either manual or electric, each of which has their pros and cons that we’ll get into later. However, I can tell you now that the grinder is the most important accessory to any vaporizer because you can’t use the vaporizer without it. So, now that you know that, let’s take a closer look at herb grinders.
- Can be easily used by anyone
- It’s a little easier to calibrate the consistency of the grind
- You never have to worry if they are charged or not
- They include their own receptacle to catch and distribute the ground herb
- The good ones rarely, if ever, need cleaning
- Most of them include kief catchers to collect some of the most potent parts of the herb
- They are more portable-friendly than electric grinders
A grinder will break down the herb and give it a greater surface area so that it better fills the oven of the vaporizer. This allows the oven to evenly heat the herb, which improves the flavor and vapor production of the herb. Thoroughly ground herb also provides a better high because the terpenes and cannabinoids present in the herb are released more efficiently. Well ground herb also improves the airflow of the vaporizer and makes it easier to access the vapor because the heated air can pass through the ground-up herb more easily.
Manual or electric is the main concern here since they are the two types of weed grinders from which to choose . Manual grinders require some elbow grease of course, but they are pretty easy to use and they have a few advantages:
The Otto Grinder is an Electric Grinder that can adjust the grind automatically based on the type of material being used. It works excellent for spliffs (the herb slides directly into a cone), but your vaporizer will love it too because of how evenly it grinds any type of herb. Overall, the Banana Bros OTTO is the best automatic weed grinder of 2020.
The Santa Cruz Shredder is one of the better grinders I’ve used because of how simple it is to use and how efficient the grind is. It’s pretty expensive, though, and it involves more cleaning than I like. Despite those problems, it’s easy to admire how well-engineered this grinder is when you use it. It turns super smooth, and the consistency is perfect for vaping.
The Tectonic9 is a manual grinder with an electronic dispensing action that makes it easy to use while keeping it portable-friendly. The grind consistency was good, and you can drop the herbs directly into your vaporizer. However, the additional complications involved with operating this grinder, plus the fact that it needs to be charged, means that it is not for everyone.
