Summary: -IGN:"Recommended almost without reservation." -I've still got my MX500. It still works, perfectly, after 12 years. -Product heritage: MX500 -> MX518 -> G400 -> G400s -I worked tech support for a major computer manufacturer
Pros: -Long-lasting left-click and right-click -Perfect weight, slightly heavier than the G400s -Good feel, slightly "tackified" sides for good grip -no "open palm heel area" which you get with the Razer Deathadder
Cons: -polling is about 125Hz -800dpi -not ambidextrous: designed for right-handed gamers/users -optical -no longer being manufactured
Summary: This is my 3rd Logitech mouse, the one I replaced still works, just wanted a nicer/updated model. My 1st Logitech mouse lasted over 5-6 years w/heavy use. Replaced it only cause left click wore out. I hope this one lasts that long.
Pros: Finish, matches my other components that are black/silver. Easy to setup, comfortable feel. Installed in WinXP Pro and in Xandros 4.x w/no concerns. Even in Xandros [Linux] it detected the mouse as the MX500, and gave me the option to adjust resolution, etc.
Cons: Thumb buttons took some get'n used too, first night i used it i kept hit'n them; no problem w/them now though. Be nice if the MX500 had a backlight in blue on buttons and logo to match my G11 keyboard.
Summary: I've used this mouse for about 6 weeks now with my Logitech G15 gaming keyboard and it's a winning knock-out punch for me in WoW, EVE, UT2004 and all my other games and applications.
Pros: Very comfortable ergonomic design, great positioning of buttons, very elegant feel. The sensitivity is amazing and the mouse controller software gives you a vast amount of configuration options including multiple profiles for different games. Logitech scores again.
Cons: Install the mouse software BEFORE hooking up the mouse, otherwise you might be in for an annoying time when you get your new mouse. Other than that, no issues!
