Query: works great on Nikon 70-200 f2.8 vrii

I purchased this for my Nikon 70-200 f2.8 vrii so that it can double as a "macro" lens. Instead of spending another $1k for a 105 f2.8 macro, this close up lens works great for my 70-200. Without this, my lens need a minimum of 5 feet to focus. With this, I can go in to almost one feet and zoom in at 200mm and take very sharp pictures. I do not have a real macro lens to compare, but it works good enough for me.
