I have pretty bad arthritis. Even those hand crank grinders are hard to use because you still have to screw/unscrew them. This grinder uses a magnet. Not only does that make it incredibly easy to load but it also plays a pretty important role in helping this thing work without jamming. I have found that as long as this thing is used correctly, it truly does never "jam".1: Loading. You absolutely can not overload it. Do not put more than 1g in. It says 1g capacity right there in the product page title, so this isn't a secret. Also, break it up a little bit. If it's very dense stuff, nothing bigger than a large pea. Fluffier stuff has a little more leeway. Lastly, only place herb in the open spaces on the detachable piece. When putting it on the grinder, don't force it down all the way if it doesn't want to sit that way on its own. Forcing it just compresses the herb making it harder to grind. The magnet will hold it as long as you don't overload it.2: Grinding. This grinder was designed to be used in both directions during normal operation. If you press the button and it stops, you need to change direction. It's not jammed. You may need to do the back and forth a few times before it starts grinding smoothly, but that's how it's supposed to work. This is why it never "jams".3: Storing/Charging. This is the one thing I don't like about the design, and also what I suspect may be a potential fire risk. The grinder is designed to be placed on it's back, pointing the funnel straight up. That's also where the rocker switch is. Now if you place it on a flat surface, it's fine. The switch won't get pressed. But there's not much clearance. A little bit of debris is all it takes, and it's a very sensitive switch. Here's what makes this a hazard: When the motor is overloaded and stalled, it's completely quiet. I haven't opened it up, but if there's no overload protection on that motor, it will sit there stalled out until it overheats. If you put it down wrong and it's "jammed" you could very well not notice.Luckily, the mitigation is easy. Just place it on it's side when you're not using it. Still, this is something I would like to see the manufacturer address in future versions of the product. At the very least, add a thermal fuse to the motor on the current version.All of that said, the ease-of-use alone is what gets 5 stars out of me. This really is the most accessible grinder for folks with hand strength/dexterity issues.

What a nifty little thing! I love it.

same thing that the other "few star" reviews say... worked fine for a year... now won't even take a charge! disappointment!!UPDATE: decided to go ahead let my curiosity get to me and opened the unit up after it stopped working. What I found was an easy fix... and maybe it will help others here. The solder on the bottom of the rechargeable battery 🔋 was no good. Whoever they have soldering needs to work on their weld quality. Basically the wire broke away from the weld and therfore stopped working. If you are knowledgeable enough to do so... this is how you can fix it. (See image)
