MambaOriginal 1g Gray USB Electric Herb Grinder. Small Portable Metal Herbal Grinder Machine & Spice Mill for the Kitchen

I have had several surgeries on my right shoulder and need yet another. I have been using various manual grinders all with pain in my arm. This device allows me to grind without hardly any pain.

It is absolutely ridiculous how well this works ! Coffee grinders, and the three level grinders that catch the 'KEIF', WHY?This leaves little to NO microscopic particles the disintegrate the moment fire hits it... Amazing to roll perfect joints if you're old school like me... Definite buy...

This is a great product for personal use. The tools it comes with are super helpful battery life is wonderful and just a great addition for anyone that likes to relax and live. Now we just need them to make a larger one to handle more. You will not be disappointed!!!!!

It looks from photos like it would be self-contained ( and so eliminate mess) but it's not.

3 - 5 grinds in the Mamba gummed up and was stuck. After cleaning I'm grinding again. This Mamba is Louder than my other two, I don't like that.

So far so good. Grinds stems and all with easy. Does not sound like motor is bogging down during grinding.

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)

It's slow but is way better than a sticky manual grinder. I have only had it a week so I'm not sure how it does at the sticky phase yet.
