I bought a
coffee grinder last year and did a little bit of research. Although the Porlex was the one with better reviews, I found it too expensive. Chinese-made grinders got very bad reviews. So I decided to go for the Hario Skerton (second edition) and I was lucky
enough to find it on sale. I think it cost me 35€.
So far it's worked pretty well. You can select different sizes, and even the coarser ones are quite homogeneous --this matters to me, since I use different coffee makers that requires different coarseness. I don't expect it to last a century like the pics above, the lid is made of plastic and there's rubber all around, but if it makes up to ten years that would have been a good purchase. The family is enjoying the extra aroma on the coffee, but the work of grinding they leave it all to me.
