Razer Deathadder. Either the 3.5G or the 2013 edition.
There are a couple of reasons:
- They're extremely durable. I have the 3.5G for a year now and nothing's broken about it. Also, the 2 keys on the left are so usefull for playing games while playing music because you can set them up to do a lot of stuff, including play and next track. So, if you're playing a FPS wich requires pinpointing, you can pause the music while in that type of situation.
- It's really, really good. There's no microsoft jump, feels really good in the hand (I have quite large hands, but this also fits smaller ones) and the "skin" feels really good. Also, when you're eating chips or any other greasy food, it will stay greasy for a while but after a night or so, it will go away.
- It looks good. Yes, you can't change the mouse colour but the Razer logo going fading in and fading out makes it look really good when it's nighttime.
Overall a great mouse, so I'd go with this one.
