## Customer Reviews

### ⭐⭐⭐⭐⭐ A must have on the road & camping!
*by N***T on March 10, 2023*

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.

### ⭐⭐⭐⭐⭐ Grinds WAY better and faster than expected
*by K***D on August 15, 2023*

It’s a really great product, but we had to be REALLY careful. The description seemed like you held down a button while it ground and released to stop, but it’s touch-start and stop. It’s also VERY sharp, fast, and DEFINITELY makes the whirlwind described which is all good; but it grinds a bit faster than expected so we have to watch carefully and ALWAYS stop it before the instructions say to or we end up with unusable powder for things like coffee (it’ll go straight through the filter or clog it depending on filter type).So basically the pros are also cons, but as the blades eventually dull I’m sure it won’t be as big a deal. In the meantime it was wonderful to find a grinder that actually works well and didn’t have to be shaken while in use to get an even grind

### ⭐⭐⭐⭐⭐ I broke my glass jar, Where can I purchase the glass jar.
*by D***S on May 27, 2025*

The item works GREAT! Unfortunately I broke the glass jar. Does anyone know where I can purchase a replacement glass jar?
