Tried two of the separators with movable parts, and both broke. This one might not be fancy, but it definitely works the best. Removes about 90% of the fat, so there's little waste of broth. Love the four-cup capacity, which saves lots of time when separating large amounts of liquid, like for soups. My only criticism is with the size of the holes in the top strainer. Why so big? Smaller, it wouldn't be necessary to strain the liquid again. If not for this, I'd have given it five stars.
