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

This is the second one I bought. The first one somebody wanted it worse than I did I guess but it worked like a charm. Grinds the flower up just perfect for rolling up and smokin. And this one that I just bought works just the same. It's also perfect with the way that the chamber is tapered, you can grind the flower right into your pipe effortlessly. Excellent grinder!

I've had this since Sep 28th, I use it to grind my weed because I got tired of twisting my grinder by hand. This works wonders! Haven't had a problem with it so far. It will stop because sometimes I pack it a little tight, just go back and forth repeatedly until it broken down and can go perfectly in one cycle. I hover it over my tray and it pours out, after im done i open the cap and get the rest that built up (takes me less than 2 mins) after that I put it away. Battery life is good since I don't grind weed often. Charge it a little bit if I feel it's getting low and ain't powerful enough to work, gets the job done less than 2-3 mins

It ground 3.5g in 4 loads, quick as a wink. So easy to use and what a relief for my arthritic hands. Beautiful results.

This grinder is amazing. I was injured and broke my arm so grinding my buds was out of the question. This has worked AMAZINGLY through about half a p. I only knock one star off because of how much gets stuck in the downward funnel. I attached pictures. If it weren't for this then id be tossing full nugs in a bowl and acting like it was appropriate, just like Alex used to do.

This is by far the best grinder I have ever bought and used! It is easy to load and easy to turn on and off. It produces the perfect grind, not a powder and no large bugs, just a bong friendly grind that is perfect. Thank you for making this. I recommend it to everyone.

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.

Works great! And the charge lasts a long time

Great little grinder for small amounts at a time. When loaded full, yes it sometimes hesitates, jams, but just flipping the switch forward and backward a few times, it frees the jam and does the job. I was a bit dismayed when grinding some herb that was on the moist side. It did grind it, but gummed up the grinder blades so bad that after 3 loads, it was grinding so inefficiently that I had to stop and clean it. THAT was not easy. The sticky residue coated the blades and was difficult to get off. Alcohol wipes, and Q-tips soaked in alcohol worked, but not as well as WD-40. Of course you don't want WD-40 residue in your herb, so don't use that regardless of how well it removes sticky herb residue. I looked into this problem and discovered that virtually ALL grinders this style gum up with moist herb, regardless of how expensive. So, bottom line, use this little jewel with dry herb only OR you'll be spending more time cleaning the knives than actually grinding herb. I would recommend this for dry herb, and would buy it again. Only gave it four stars because of how hard it is to clean, although I'm not sure how they could make that easier given how it operates.
