Mamba Original 1g Black USB Electric Herb Grinder. Small Portable Metal Herbal Machine & Spice Mill for the Kitchen

I do not have pics, but this grinder works really well for mushrooms. You can only do a small amount at a time, but I know if I tried to use it with flower it would be perfect. It’s super easy to use, I just turn mine where the hole is at the top, and I move the grinder left and right to get a really fine grind. I’m not sure how long the battery is, but I’ve used it at least 5 different times and I didn’t need to recharge, so I’m going to assume it has a pretty decent battery life. This is an amazing value for how cheap it is too!! To clean the machine is kind of tricky, I’ve tried to wipe it down but, in all honesty a can of air, or running water over the top part is the only efficient way to clean it. I’d definitely say it’s pretty durable, I’ve dropped it and it hasn’t broke, and I didn’t overload it with mushrooms to see how it would work, and it did not break, very sturdy.

I've had this for years and it still works as good as it did when it was brand new! I use this if I'm just grinding for myself because it doesn't grind a ton of weed at once. The cannabis comes out perfect for my taste! Will definitely buy another when this one stops working! Can beat the cost for the quality you get!

I love this grinder! Its strong and easy to use. As for the battery life, I can't say enough. I've had it a year and haven't had to charge it yet! Amazing!

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

This works well for older people with hands that can't grind like they used to. Recommend it for any older adults with the same problem. Easy to use too.

This is the very best grinder that I have ever used. So much better than twisting and twisting . I would buy this over and over again

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)

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.
