If you want something stylish that looks phenomenal on your desk and has a few extra buttons, you just simply can't beat this price. Even some low quality office mouse with no responsiveness at all is going to cost you more than eight bucks at Walmart.
Besides your standard scroll wheel and side buttons, this one has a DPI scroll wheel, letting you change the mouse sensitivity on the fly for playing different types of games or using different modes within FPS games.
There's a downside for the price, however, as the buttons aren't placed as ergonomically as they could be. And the LEDs cycle through a breathing pattern rather than sticking to one color you like.
