I have been using my Logitech MX310 for a bit over two years but it's starting to show its age. It has served me well but 800 DPI doesn't do me much when it comes to precision aiming in shooters. I need a mouse with a similar design to the MX310 but something that is more precise and has a higher DPI. I like my mice to be on even level instead of the concave/convex designs that are so popular these days. If you have owned a MX310, you'll know what i mean. Thanks.
