Why did I bought this mouse ? Hmm because I used to have a sucky and expensive Logitech one that broke ! I was so surprised, it costed me like 80€ and broke in less that 5 months. That's why I looked on the web for a good mouse. I found some pro-gaming sites, seen some pictures and realised most of them got this mouse ! The Acid Green Razer Diamondback mouse ! You can check on your own : Grubby, Moon, Sky (Warcraft worldwide known pros) they all have that great mouse !
It's a mouse for pros players, no doubt. It's quick, easy to use and -the most important point- designed for long gaming times ! It has a wire, okay, it may look like a bad point for some, but come on ! Haven't you ever played more than 5 hours of video games ? Didn't you feel bored of having to stop playing cause you had to be sure the mouse would have enough energy to keep on playing ? Yeah ! I did too. That's why I bought this awesome mouse. It has many buttons that you personnalize (with hotkeys or even your very own personnal macros)
The green light doesn't hurt or catch your attention at all. The mouse design is perfectly made for your hand to match.
So, just try it, you'll see the difference.
