Works great. Easy to setup and fast response time.

I have been a hardcore fps gamer for more than 10 years. this is the BEST "Casual" gaming mouse for me. pro 1.battery life is insane, way better than the g403 or g703 2.robust as fuq IMO logitech>steel series > razer 3.

My Son is well into his gaming ad this mouse is exactly what he wants,very pleased with it

This mouse is slower than my G203, good for casual use but not fast enough for competitive FPS gaming. Battery life, portability is amazing, but still not 100% in performance/reaction time.

The tantalizing prospect of freeing your mouse from its unwieldy tether is easily attainable for most casual PC users, who can pick up a decent wireless mouse for less than $30.

They must face a painful tradeoff: Eliminating the physical connection between mouse and PC ensures greater freedom of movement, but usually at the expense of the accuracy required for fast-twitch gaming. The new Logitech G603 Wireless Gaming Mouse ($69.99) is no different. Although it boasts Logitech's improved 2.4Ghz wireless transmission technology, it still suffers from occasionally noticeable lag even when performing everyday non-gaming tasks. Gamers who value pinpoint accuracy above all else will want to examine the Logitech G Pro ($129.95 at Amazon) , our current Editors' Choice for gaming mice, but if your biggest pet peeve about PC gaming is a constraining mouse cord, the G603 deserves a close look. Few Buttons, but Easy Customization The G603 is rather plain, e...

If you're willing to give up lighting, oodles of buttons, and extremely precise control for greater mousing freedom when you play, the Logitech G603 won't disappoint.

Good accuracy for a wireless mouse; Unobtrusive design; Long-lasting battery; Easy-to-use customization software

Lacks lighting; Only five buttons

Logitech has been around for a long time and there is no question, they have an established track record of delivering high-quality mice.
