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

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

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.

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.

Really good, the lag is unnoticiable during competitive fps gameplay

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.

Have been looking for wireless options for a while now but unfortunately I will probably have to wait a few years or two more. Current Although I praise the possibility of replaceable batteries, the mouse becomes too heavy. Why so big batteries when the battery life is obviously good enough

The Logitech G603 wireless gaming mouse is cut from the same cloth as the G613 keyboard. It's plain and practical, and isn't intended to grab much attention.

Today we kick off a trio of Logitech reviews; we'll be taking a look at their latest in the war against wires; the Logitech G603, G703 and G903. We'll start off with the Logitech G603, designed to be a budget option offering gaming performance with the option of also extending battery life to 18...
