This coffee grinder does what it says. It definitely grinds coffee and I like that it has settings to adjust how coarse/fine it can be. I gave it 4 stars because while it does grind, it is manual and my hand began to hurt. I think I would prefer an electric grinder if i had a choice.

I was excited to receive this coffee grinder, but so incredibly disappointed when I opened the box. I was even more disappointed when I attempted to use the grinder. The knob to adjust the courseness or fineness of the grind does not seem to work. Also you have to lift part of the silicone lid (which gives you a very small opening) to put the coffee beans in to grind. If you want a larger opening to insert the beans, you have to remove the entire lid by unscrewing the handle, which involves removing several parts. All in all, I think this is a cheaply made product.

Ya get a good arm workout.

broke after two months. handle snapped. cheap

Tried to grind chia seeds. Did not work at all at any setting.

I've just purchased this. After using it for my morning coffee, with my fresh Ten Boom coffee beans (or any fresh roasted coffee beans you might like!), I'm a believer! This grinder was simple to use, didn't hurt my wrist (which is prone to be wrinched easily), and I tried a couple different degrees of grindings just to test it. I'm super excited to use this from now on.

Cumbersome to use

Got one about 3 weeks ago. Used about 4-5 times a week. The handle already sheared clean off at the screw. It's almost a relief because of how long and much of a workout it is just to grind enough coffee for one cup. Will be investing in something of higher quality next time.
