With this arrangement, the Logitech G903 can pull a constant current of electricity to both power its operation and recharge its internal batteries. Not only that, the PowerPlay mat comes equipped with a wireless receiver that connects with your mouse, so you won’t need to occupy another USB port for a separate dongle – which you can instead plug into a laptop.

First is its use of the PMW3366 optical sensor. This isn’t a unique feature, but the sensor is one of the best on the market and means the G903 has a fantastic 200-12,000DPI sensitivity range. Personally, I’ve never had a need for five presets, and generally limit myself to two: one for office work, one for gaming. But I can see the appeal for more hardcore gamers, who want specific settings for different genres. 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.

The Logitech G903 might be a wireless gaming mouse, but it feels as seamless as a wired one. That’s no small feat, and that’s all thanks to the same Lightspeed Wireless technology that was also in the G900. We never experienced any latency or loss if signal despite using the peripheral in an office saturated with Wi-Fi, Bluetooth and every other type of wireless signal. Outside of this, the only difference between it and some of Logitech’s cheaper offerings is that the G903 has local memory that lets you save up to five different profiles on the mouse. You can toggle through the various presets manually using a button on the bottom of the mouse. RF antenna is designed specifically for LIGHTSPEED for absolute minimum impedance and maximum signal strength. RFIC: Radio frequency integrated circuit transmits MCU data robustly and reliably via fine-tuned electrical pathways.

Performance is an area in which wireless mice have traditionally always fallen behind. They’re generally less responsive and more prone to latency than their cabled brethren. Fortunately, this isn’t an issue at all with the G903 for a few reasons. MCU: Microcontroller unit translates data from the processor, via enhanced firmware, faster than ever before. Get ready for endless gameplay. The POWERPLAY wireless charging system keeps G903 and other compatible G mice charged while at rest and at play.* Just attach the included POWERCORE replacing the optional 10 g weight and cover. Never worry about battery life again. TIP: We recommend using the cable and adapter when you’re in wireless mode. This allows for better connectivity and easy access to the cable when you need to recharge. The end result is one of the best mice I’ve tested in performance terms for competitive gaming in quite some time.Logitech G engineers worked through a complete end-to-end technology optimization from sensor to firmware, circuitry to antenna. We tested and refined each component, focusing on the slowest link until nothing was slow.
