Pros: 3 Button DPI on the fly, The forward and back button placement.
Cons: Nothing I can think of.
The mouse has a macro feature for assigning difference buttons to different things which can be done threw the software. The on the fly DPI can be changed in steps for example of my settings I have it set at 1000 DPI on the lowest, 1600 Middle and 2000 DPI Max. The button with the logo on it originally opened the mouse settings menu when I first bought it but after a software update it was changed to open the games menu.
The red LED lights at the back of the mouse make it perfect for someone who's into the whole red and black theme like myself. The overall shape of the mouse is comfortable, I would recommend this mouse to people with medium to large hands as my family has small hands and they find it uncomfortable.
Overall I find this mouse great and if your ever looking for a cheap mouse and can get your hands on one of these I would recommend you get it or if you want a mouse with more features get the Sidewinder X8.
