It grinds coffee well. The action is fairly smooth, although there is a perceivable little skreech with each turn of the handle. The lid it comes with means that once grinding is done, you just unscrew the mill part and put on the lid. It makes an attractive is small capacity store for the coffee.The rubber removable base prevents it from slipping, if you are using it on a table top. However, used in that way, you still have to grip the grinder with one hand to stop it moving about, and that does result in an ache after awhile. I find it easier to grip the grinder between my thighs and grind with just one hand. The coffee itself comes out ground to perfection.
