Designed with the world’s leading pros. Engineered for pure performance and nothing in the way of winning. That said, as convenient as the PowerPlay is, it isn’t going to get the Logitech G903 fully charged in a jiffy. Going from 0% battery to a full charge with your mouse on the PowerPlay would take between 12 and 14 hours, by Logitech’s estimate. Make your play with 15 programmable controls, blazing fast LIGHTSPEED, and precision HERO 16K sensor. Your mouse uses a USB gaming receiver to relay wireless signals from the mouse to your computer. To optimize the wireless connection, plug one end of the cable into your computer and the other end into the USB adapter and receiver. You can also plug the receiver directly into your computer.

To many, this peripheral might seem like a premature sequel. However, its ability to constantly draw power from Logitech’s new PowerPlay mouse pad could solve one of the last annoyances of wireless gaming mice. The only lighter option you’ll find is the even more expensive Razer Mamba + Firefly, which uses similar wireless charging tech to let the mouse operate without a battery. It weighs just 96g as a result.On plugging the 2.4GHz Lightspeed dongle into a spare USB 3.0 port, the mouse instantly connected. Since then it’s offered an entirely latency-free gaming experience that matches many of the wired sets I’ve tested for responsiveness – and is completely free of the bugs we experienced when testing the competing Razer Mamba + Firefly. The mouse can also be connected to your computer using the supplied USB charging cable. Your mouse works in data-over-cable mode when it’s plugged into the computer. This connection also charges the battery. If money is no object, you’ll struggle to find a better mouse than the Logitech G903. Thanks to the addition of Logitech’s Lightspeed technology, it’s one of the most responsive and reliable wireless mice available. Play the next dimension. Impossibly thin. Incredibly feature-rich. GL low-profile mechanical switches.

Up top you’ll find basic buttons to adjust the G903’s DPI, and switch between a smooth or step action on its wheel, plus the usual left and right controls. The end result is one of the best mice I’ve tested in performance terms for competitive gaming in quite some time. The G903’s stellar left- and right-button mechanical pivot hinges round off its performance benefits. The switch mechanism is one of the best around and has a wonderfully light actuation point. This makes the mouse feel insanely responsive and fast.RF antenna is designed specifically for LIGHTSPEED for absolute minimum impedance and maximum signal strength. The idea here is to let gamers set up the mouse for either their left or right hand – which, as a lefty myself, is very welcome indeed. You may even choose to go all-out, and have four side buttons – although, personally, I think that’s overkill, even if you’re an avid MOBA or ARPG player. Some will argue that optical sensors are better than five-year-old laser technology, meanwhile, on paper Razer has a leg up on the sensitivity department. Ultimately, though, after using both mice for a week at the same time, we can confidently say they’re both equally as accurate and reliable. In terms of physical design quality, both the Logitech G502 Lightspeed and the G903 Lightspeed are top-notch. Both mice are built to last with sturdy frames and materials, and both come with 11 buttons that you can customize as in-game macros. Starting with the basics, the G903 comes with up to 11 keys, depending on how you set it up. Out of the box, there are two extras on its left side and an option to add two more to the right using a magnetically attached plastic plug.
