I've been through plenty of mice in my life. Comes with the territory of being a nerd. We've had 2-3 computers in our house for as long as I can remember, all with different mice (until someone complained X was better than Y, so we'd buy 3 X's). This went on year after year. Plenty of CS-induced rage attacks, little kids and late night snacks killed many a mouse, so we've been through A LOT.
After almost a decade (literally) of "product testing", all of use agree, the G500 is without question the best mouse for your money. You're probably looking through these reviews trying to figure out why you shouldn't buy that flashy D34tH Add3r 1337 XTREME edition with 27 pulsing LEDs and 1,000,000 DPI. Maybe that interests you because you like to draw attention to yourself. In that case, buy it. If you want quality, however, and not only the best but time-tested quality, stick with Logitech. From there, as I've said.... buy a G500. The weights, the ergonomics, the scroll wheel, profiles, the plethora of buttons.. you can't go wrong. You'll thank me, the other reviewers, yourself and Logitech. And if you don't like it? It's Amazon, the best company in the world. Return and then get that XXXTR33M3 RATTLESNIZZLE KILLER PR0. At least you'll look "cool".
