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

Really good, the lag is unnoticiable during competitive fps gameplay

We've made no secret of the fact that we thought the Logitech G403 was the best mouse ever released when it hit the market in September 2016. It's the one we've chosen as our daily driver ever since then, even though we've had a whole lot of other high-performance mice available to us.

Mind-blowing battery life; excellent wireless performance; fantastic price

No RGB lighting; heavy when using two AA batteries; no side grips

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.

Full size mouse- lager than I'm use to but very comfy. Love Bluetooth and 2.4Ghz connections, connects Instantly over both with one button press. Weighty with two batteries but works with one. Highly recommend

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.

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.

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

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

Nowhere do I see technology's relentless progress more these days than in wireless mice. When I was in college, not all that long ago, I had a wireless mouse for traveling. It cost me $30, and it barely worked.
