Pretty good.

I love Krup machines. I love the Krups brand.I've always found that whatever they've made was exceptional.
They make very sturdy and reliable machines, and for me, a person who doesn't like shopping and prefers to buy a new product once every decade if possible that's a huge plus.

I bought this coffee grinder after my Bosch coffee grinder's plastic lid fell to the floor and cracked.
I decided to pay a little extra and go with a brand I hoped would not have similar reliability issues.
Like other Krup machine's. It doesn't make you fall in love with it at first. It's very utalitarian. But it's strong and reliable, and slowly it grows on you, as it lasts in your kitchen longer than the other machines that are much more flamboyant, but eventually break.
The coffee grinders engine is strong, fast and grinds the coffee beans efficient. You can press the button long enough for it to be totally grinded to small particles, or you can press the button several times, to create a pulse motion, and get more coarse grinded beans.
I've had this machine for three years, and the engine runs perfectly.
My only complaint is that one has to scoop the coffee out of the unmoveable grinder, from underneath the blades. I know it helps it's durability and reliability, but in terms of ease of use, they could have invested a little more, in finding a way to make the grinder cup removable.
