This is a very good budget gaming mouse. Yeah the DPI settings aren't the greatest, but hey - what do you expect for a tenner? It is very ergonomic and stylish and more to the point, the two extra buttons on the side of the mouse come in VERY handy when playing games. They can also be used to navigate forward and backwards through pages on the internet.
All in all, I would definitely recommend this mouse to any gamer that doesn't want to spend a small fortune on a mouse, and to any non gamers as well due to how comfortable it is.
