Mamba Grinder Electric Spice Grinders. Easy to Load One-Handed Use 1g USB Rechargeable Mill

I love this device! It holds a charge really well and gives a smooth, consistent grind every time. The reverse button is a game-changer for breaking up those super dense nugs, and it cleans so easily. I’ve had mine for over a year and it’s still working perfectly. Highly recommend!

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.

I have MS and losing the use in my left arm and I couldn't use my hand but this product has helped me so much grinds very well

Very good product works great

UPDATED REVIEW: I was originally concerned about this being made from "cheap plastic." And stated that I "Doubt this will last long." After using it for a week, I have to admit, it easy to use, strong at grinding despite being plastic, and is working better than expected.

I have very mixed feelings about the "Mamba Original 1g Black USB Electric Herb Grinder". My aging hands disliked the effort to use hand grinders so I finally chose this electric grinder as a replacement. Timely arrival and very similar to the product photo page. However, if I could do it over, I now know what I didn't know before. First, I would order a 2 gram or bigger grinder since this 1 gram grinder only handles tiny bits of herb that must first be pulled apart and then inserted into the grinder teeth similarly as in a mechanical grinder. The grinder did do an excellent job of reducing the herb to tiny pieces and the forward/reverse button is very useful in the process. Secondly, I would order a grinder with metal teeth as this one uses plastic teeth on the removal half and metal on the permanent half...I suspect the plastic teeth may erode quickly with use. I have only used it once to reduce about 7 grams of herb but I sense that the all plastic construction, the demand on the battery, and the inside gearing portend a short life. It worked OK the first time albeit the user still must reduce the herb to smaller pieces that can fit in the mixing area around the teeth...I just have little confidence it will stand up to periodic use.

Out of the box, its great for the price. Its all plastic, so i don't know about longevity. charges with USB C, its light, the level of noise youd expect for a grinder. It grinds to a perfect consistency, it has a "forward and reverse". I use it as i would a manual grinder, a back and forth motion. i am pleased with the purchase. I would recommend this as inexpensive option.
