Mamba V2-50 1 Gram 50mm Electric Herb Grinder. 1500mAh Li-ion USB Rechargeable Fast One-Handed Mill. Easy Press Two-Direction Rocker Switch for Potent Product Grinding

I have carpal tunnel in both my wrists and using a manual grinder becoming extremely hard so I got this. And it's FANTASTIC. So easy to use. Does not weigh to much and it sits perfectly on it's back ready to fill and start. And the stuff that comes free with it brill

THIS BEST GRINDER I'VE EVER PURCHASED. So I purchased this fantastic grinder some time ago, it is used every day. It is well worked. I noticed a slight problem with it and thought I'd see if the part was first available as always on Amazon but couldn't find it. So I emailed the maker asking if they sold them, I enclosed a pic of problem, the very next day (TODAY) I got a reply, they are sending me it out today FREE OF CHARGE. It is without doubt the best customer service I've ever received. THANK YOU THOMAS @ MUMBA. my friends will be now getting a mumba a Christmas me thinks 😉🎉🥰

This thing is a beast great product

Works very well, makes the job quicker and very easy than typical grinder or fingers but still needs cleaning obviously. I Would buy it again seems nice and strong to last a while also very easy to use.

Battery last for months Powerful as hell Hardy piece of kit - like a tradesman’s drill, -drop it, bash it, throw it at the cat - I still not broke it yet

I like the way the contents fall in a specific area and not all over the place like a traditional grinder. Much easier on my hands too. Don't over fill, as the cap didn't stay on with too much in there and it went all over the place. My medicine is expensive, so that wasn't great, but it was user error.

Love it! So much faster and better, no more stuck grinder. You can just rock it back and forth. I lose strength in my fingers so it's very useful for me. Would recommend it to everyone especially if you have arthritis, carpal tunnel etc.

Works well grinds up fine, have to hold it up to get a finer grind. Cleans easily. Only issue I have is how loud it is, would not take it out and use.

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!

Works like a charm. So much better than a hand grinder. Well worth the money.

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
