One pot grinder
Unit holds enough grounds to make one pot at a time. I was expecting a bit larger. But it works good enough for the mis-bought beans instead of grounds.

Good grinder
I’ve been enjoying this grinder. It’s easy to use. I’ve been using it every day and I have run into any issues. This is a great deal and would definitely recommend it.

Works well, easy to use
Great little hand grinder. So much easier to use than the last one I purchased.
I moved and both of my electric grinders & my hand grinder are still somewhere in storage.
This easily portable gadget has been a lifesaver at a decent price. Seems sturdy enough after using it a few weeks.

Better than expected
This thing is great. I wasn't sure what to expect for the price, but it exceeded my expectations in every way. I have no complaints, quality is fine, the grind is fine, it's easy to use. I've used mine every day since I purchased it and it works good as new. This is my first manual burr grinder, so there could very well be better ones out there, but I am very happy with this purchase.
