Query: Disappointing juicer

This juicer doesn't handle larger pieces of fruit at all well because the pressure-applying surfaces are too small. With a medium-size orange or even a large lemon it leaves a considerable amount of unsqueezed flesh around the edge, so I can't imagine using it with a grapefruit. It also requires a lot more downward force on the handle than I expected. Works great for those little Key limes, though.
