Pros: It works really well, long cord (and durable, I don't know how many mice I've gone throgh because the cord was flimsy). The light up feature is nice, there is a button on the bottom you can use to change it to three colors. It's actually a pretty stunning looking mouse. I use it for high detail graphic design and it does a great job. I use it for gaming and I don't necessarily need all the extra 'macro' buttons, so I'm not rating it for that. They dont' get in my way, that's what I care about. The wheel works really well, and is smooth, though it is not the smoothest, and it has grooves (I wish it had no grooves).

Cons: - The mouse flashes constantly, it doesn't actually just stay on solid. - if you are using this on a laptop that doesn't have a tray that comes out, the disc is a tiny tiny disc that may not register (and I have a really high end laptop). So I had to search for the drivers manually. -Every time I plug it in it seems to need to 'find' the drivers again, so I have no mouse capabilities until it finishes that -There is no way to put the mouse to 'sleep' and have the mouse go dark.
