On the surface this pepper mill had it all... nice sturdy look, large capacity, and an easily selectable grind size. I'll say up front that we cook a lot, so the mill got pretty heavy use. It worked great for about a year, then the plastic parts cleverly hidden beneath the metal top began to disinegrate. It still works, but I'm not sure for how long... and some of what I think is pepper on my eggs may be ground up black plastic. Seriously though, I'm changing brands.
