Having a wireless gaming mouse is all about accepting compromises: along with superior mobility, freedom, and performance, you also have to deal with frequent battery recharges. As one of the Titans in the world of gaming peripherals, Logitech has several solutions to this problem.

Really good, the lag is unnoticiable during competitive fps gameplay

There is something quite interesting about Logitech since it appears to have developed far beyond its numerous competitors when it comes to one vital feature – wireless connectivity.

As I mentioned in our recently published Logitech G613 Wireless Mechanical Gaming Keyboard review , gamers by and large stick to wired peripherals for various reasons. As we found out with the G613, wireless peripherals can easily keep up with their wired counterparts.

Comfortable; ergonomic design; Can use with 1 or 2 AA batteries to adjust weight; Fast response time; Great battery life; Lo/Hi mode to extend battery life; LGS pretty easy to use; heat map functionality included; 200 - 12000 DPI; Can save profiles on board; BT or LIGHTSPEED wireless options

A tad slippery feeling; Requires a USB port for LIGHTSPEED connectivity; Some many not like the narrower/higher profile

i used before corsiar gaming muse and this muse is one level higher, muse feel expnsive and move fast one bad things is the wights little bit havey

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 mouse worked fine when I first installed it; however, after a while, the mouse wheel wasn't working properly. When you scroll up and down, it would sometimes scroll in the opposite direction intermittently. After researching online, it appears this is a common issue with this model mouse.

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.

The G603 is probably best for someone who wants a great precise mouse for productivity, and who plays slow paced or strategy type games where it's weight won't be such as issue. The weight comes from the 2 AA batteries used to run it, although it can be run on one, I wouldn't recommend it.

Initially, I was going to return this product when I tried it on my PC. There was horrible response time and lag. By downloading Logitech's gaming software and updating the G603's Firmware, it no longer lags when using the USB receiver.
