Herb & Pill Grinding Made Easy Spice Herb Coffee Grinder Review: Awesome Grinder! - My wife suffers from arthritis in both hands. She has been disabled for the last 22 years due to a major back injury. She uses cannabis for pain relief and to help her sleep. She’s no longer able to use a manual grinder, it hurts her hands so much, so I’ve been doing it for her. I needed to find a better way for her to grind her herb so she can take her medicine when I’m not home. Then I ran across this little gem of a grinder. It grinds so much better than grinders we’ve owned in the past. We load it with quite a bit of herb buds and it pulverize’s it in seconds to a beautiful fluff. Our buds are kept at 62% humidity and the grinder blows right through it. I highly recommend this grinder for your medicinal herb if you experience pain in your hands and fingers. This is just what you are looking for so you can grind without pain. And for those people who just don’t like to grind, you’ve found the promised land with this device. It’s a rechargeable grinder via a USB cable so you can take it the car or on a road trip without issue. UPDATE—-it’s 3/14/26 and it’s still working. Too bad they do not sell them anymore. This grinder is a workhorse! Review: A must have on the road & camping! - Highly recommend this purchase to anyone in need of a great cordless grinder. Yes it works awesome on cannabis flower & grinds it to a perect consistency for flower vape, bowl or rolling. My beloved wife "had" Cancer & after 16 months of healthcareless hiccups, chemotherapy, radiation chemo & 2 surgeries, she's on the mend hovering around 85 lbs. And Yes, I contribute much of her survival to cannabinoid intake with REAL science to back it up, not fauci/political science. The grinder is also a wonderful little coffee or spice grinder. We enjoy our coffee very much too & grind it fresh with fresh hazelnut & cinnamon. Not sure what these few bad reviews are all about. I've bought 1 & recommended to 3 others that purchased & very happy as well. Be sure to keep the magnetic collar clean which is the device that allows the grinder to turn on. If it doesn't charge, you're either not sing the heavier charge cable it came with or you're not plugged into a full 5 watt USB outlet which it needs to adequately charge. So no, your pc tablet or tiny powerbank likely won't do it. ## Features - 【Material and Wireless Electric Design】: USB interface charging, 1500mAh large-capacity battery realizes high-power and high rotational speed operation, and the blade is made of high-quality stainless steel, which is very durable.

I lost the power cord. Just discovered my RING battery power cord fits it, charged it! Now the Spice Grinder is charged, but does NOT work.
