I bought this after much deliberation and a few shoddy mice (mouses?). I wanted a cheapish option that was responsive and comfortable and having read a number of reviews I gave this mouse a whirl. It is awesome! Really comfortable in hand, responsive, accurate, easy to switch dpi and has a really good weight to it. Very useful pair of thumb buttons. Used for many hours for general use and gaming, from accurate sniping to trigger happy firefights and felt great. Not sure how they are making a profit at £7.99.
