Amazing juicer. Yes it really does work with massive grapefruit all the way to tiny limes. The thing is big, heavy, and solid. Easy to clean - I've used a lot of juicers, this one is by far the easiest to clean. 
If there was one silly little problem, it's that odd clip to hold the top press part in place. It isn't the best design in the universe. But you don't have to take the top presser off very often, so it's not really a big problem.
