I’ve used this tool for about 10 years and it’s still going strong. It’s probably the best garlic press in the world. It’s constructed very robustly from stainless steel; it has an unusual lever-action which is far superior to the one-to-one action of most garlic presses; it opens up easily and is trivial to clean.
To see a demo, have a look at America’s Test Kitchen Equipment Review (below) where they come to the same conclusion.
But note that Kuhn Rikon have another garlic press called the Easy Squeeze, which is a lot cheaper. It has a slightly different action and plastic handles. It’s not nearly as good.
