so i impulse bought this as a slickdeal – $29 after rebate from amazon. i’ve had this mouse for about a week now. i switched from a MX518 – which was working fine, haha. both mouses are gaming-grade and both perform very well.
mini-review: the mouse feels nice in the hands, especially if you have a gamer grip (usually more focus/pressure with the fingers) due to the wideness. i’ve tested it in my normal games and it’s definitely responsive and accurate. the mouse’s ability to store profiles is great – having certain bindings for each mouse button is so useful and convenient.
i’m a big fan of logitech. they make great products. i have logitech z-5500 5.1 speakers, logitech g15 keyboard (1st edition), 2 logitech mouses, and some other items.
