Wow! It does work. I had a GE coffee grinder that I've been using for many years and replaced it with this Krups grinder. I think the GE used to work OK, I never noticed issues before, but lately at least cinnamon and cardamom weren't working at all. This was all very frustrating. So in desperation I bought a new Krups grinder. I had very low expectations, but it does seem that the grinder matters. I don't know if it was that the other one was old, or that this one is just better. I can say I'm a really happy customer. I emphatically recommend this product.
I paid a little under $20 for this Krups grinder at Amazon. So if you're wondering can you reach grinding heaven, the answer is yes.
