Yes, the citrus sprayer really works. When inserted in any citrus fruit - limes, lemons, oranges - it produces a fine spray of the freshest possible juice at the touch of a finger. It's great for flavoring beverages, cocktails, salads, seafood, or fish. Just trim both ends of your citrus fruit, then push the Citrus Sprayer into one end. You can then store the fruit with the sprayer in place on the stand that comes with the Citrus Sprayer. Each Citrus Sprayer is actually a set of two sprayers with different length taps, one long, and one short, to fit various sizes of fruit, and a stand to hold the tapped fruit for storage.
