ExtremeTech is one of the first sites to review the new Logitech G9 mouse. This mouse is designed specifically for gamers with a 3200 DPI sensor, on-the-fly DPI switching, profile and macro management, lots of buttons, various weights and interexchangeable grips.
According to the reviewer the Logitech G9 laser mouse performed excellent and is one of the top mice for gaming available on the market. The mouse has lots of features, allows lots of customization and good software.
Perhaps the biggest problem of this product is its price - $99.99 is quite a lot for a mouse, even if it's the best on the market.
