Nothing fancy with a lot of settings.  Just a good quality metal sprayer that delivers a spray ranging from a wide fan to a strong stream, depending on how far you depress the handle.  The strong stream works well for watering plants from a distance, or for washing window screens, which will be the primary use.  The wider spray is good for close-range watering. The only thing it doesn't do, is provide a gentle flow, like if you want to fill the birdbath.
