Great control and consistency over grind size. The ionizer noticeably reduces static and mess. Only negative is the plastic dial bends a decent amount when turning, making the build quality feel cheaper / less solid than could. Great grinder for a great price.
This was a replacement grinder that I was interested in. The Opus2 far exceeded my expectations. I look forward to making espresso in the morning and for my friends because the experience is so seamless. The only recommendation I would have would be to improve on the static cling from grinding. The case and cups are of a plastic base- I feel a metal solution would allow this product to compete with the brands I see as more advanced.
I LOVE the Opus 2! I've been using the Barazta Encore for 5 years, but I bought an Espresso Series 1 so had to make the grinder upgrade as well. I love everything about it - the look, the quickness, the grind. . . excellent!
