I had absolutely no problems using the MX 510 during general app use and during hours of gaming. It has many nice improvements over the MX 500 (and the entire first generation MX family for that matter) thanks to the new MX Optical Engine. You can't deny that it's one of the best performing mice around. Plus, it's also one of the best looking. The red, 'reflex finish' looks awesome. It's very unique and will definitely spark conversations (and envy) at LAN events. The MX 500 and Microsoft Intellimouse Explorer 4.0 look quite boring next to the MX 510.
