Works great and allows you to squeeze directly into the container or you can squeeze into the metal cup of the juicer. The metal cup is nice if you want to use fresh lemon juice for a recipe because you can measure what you need.
I've tried reamers and a couple other brands of juicer, and this is one of the most-effective (and seemingly durable). The gear mechanism gives a lot of force, and the plastic used feels strong with a little flex towards the end of the squeeze. The only breaking points I'd worry about so far are the metal pins at the hinges.Other concerns: this is really better for small citrus, oranges and grapefruit have to be quartered or cut even smaller to fit.
