Overall Review: An awesome mouse, I bought it at my computer store for the same price here on newegg, its got a nice shiny tin of different sized weights for you super hardcores and 5 assignable buttons for games. The biggest thing that made me happy is it worked on my bare desk where all other mice have failed, I hate mouse pads but other mice wouldn't work on my shiny varnished desk but this one finally does, perfectly. Unlike most mice this has 3 dpi settings instead of 2 which is also good for sniping when you need to go really slow too. My only complaint is the tilt wheel doesn't work so well with the middle mouse, often times I hit the left tilt and middle button at the same time but usually its not a problem, I am still giving it 5 eggs for this awesome mouse at a reasonable price. Comes with 8 1.7g and 8 4.5g weights with 8 slots to put them in and it can get pretty heavy for people like me who like a heavier mouse but its also pretty light with no weights. Good mouse, I love it!
