Review on Kitchen Aerator Rotatable Anti Splash Replacement by Nick Walsh

I bought this for my kitchen sink and it is 21 inches long, 15.5 inches wide and 6 inches deep. The faucet was easy to install and use. I have a problem with 360 degree rotation. Yes, it rotates, but it doesn't have a large radius. At its furthest point from the center, it doesn't even reach the sides of my shell, so it kind of defeats the purpose for me. If my shell were smaller, that would be great.
