COOL KNIGHT Electric Herb Grinder Spice Grinder, USB Rechargeable 200W Cordless for Herbs, Spices, Seeds, etc. (Black)

Loved this. Cat broke it. Couldn’t reorder at that time (out of stock) ended up with a different model that we do not like as much.

Durability. Ease of use

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.

My quibbles: the blades can throw the spices up rather than down toward themselves. So for a fine grind, I tend to shake the spices down and grind for a long time. Also, it is a little bit challenging to get it completely clean. If you don’t use it for a couple of weeks, you may need to charge it before use.All that being said, I do like it and continue to use it on a regular basis.

Worked 5 times and now blades wont engage .

I'm a daily herb-user and this grinder has completely changed the game for me. No longer struggling with hand-grinders that get jammed up, this one is as simple as pushing a button and it's fully rechargeable, compact, and can store the ground herb until you use it. Great purchase!

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.

It works. Screwing the jar on the threads is really tricky to get them on without cross threading. I bought this for my wife to grind spices because her hands don't work so well and I have to thread the jar on to the motor because she has trouble. It shouldn't be this hard to do.As others have said, the run time shouldn't be a preset amount of time. It should run only as long as the button is held down. Cut off the motor after 10 seconds if you want to design it that way, but don't let the motor run longer than we want it to and over grind with the preset run time.
