Speaking of Powerplay, we should also talk battery before we wrap this up. That’s the whole reason we’re getting this rework of the wireless G403, after all. IDG / Hayden Dingman The G703 has received the newest firmware update (version 22.2.15), increasing the CPI range to 25,600 CPI.

Using the G703 in its traditional, non-Powerplay mode, I got about two or three days of use before I needed to connect the included Micro USB cable and plug in the mouse. That matches Logitech’s figures, which list 24 hours of battery with the default lighting (or 30-plus if you go dark). Charging takes about two hours, so the mouse should be charged with time to spare if you plug it in overnight. It works. A truly wireless mouse is finally here—one you’ll never need to plug in. If you’re willing to shell out the cash, of course. Bottom line The G703 is the perfect gaming mouse for those who want a comfortable wireless gaming device that’s great across the entire range of PC games. While there’s no doubt it’s an expensive upgrade, the PowerPlay integration allows for a truly wire-free experience.Some will want something a mouse that’s more flashy; others a mouse that has a greater number of buttons.When it comes to performance, there’s plenty to praise here – and very little to complain about. I’ve been playing hours upon hours of XCOM 2 and Player Unknown’s Battlegrounds, and have been loving every second.

It also uses Logitech’s proprietary “Lightspeed” wireless tech. Time was, a wireless mouse was verboten in gaming circles—prone to interference, plagued by bad sensors, people wanted wired mice because they were dependable. There’s also an assumed benefit to wired: speed. Surely nothing’s faster than an electric signal over a wired connection, right? Lighting Zone Selection: Apply light settings to the G logo, scroll wheel or both. You can also disable the lighting.

That feature seems admittedly more useful on the higher-end G903, which glides effortlessly across the mouse pad. I actually thought the G703 was the heavier mouse at first, due to how much it dragged while moving—but no, it’s actually 3 grams lighter than the G903 (107 versus 110). It’s slow, sure. If you need to be somewhere in an hour and don’t plan to take the mouse pad, you’ll probably want to plug in the G703 directly. Is it unusable? Far from it, and a few may even prefer the G703. That drag allows for more precise movements, at the expense of slightly more effort. For my money though, I prefer the G903, or really any mouse that glides without a second thought. IDG / Hayden Dingman The Logitech Gaming Software is up their with the best; it’s clearly laid out, and easy to use. It’s here that you can change the performance settings of the mouse, and reassign buttons to other functions. The RGB lighting can be altered and synced with other Logitech peripherals, but I do find that Corsair’s CUE software has more effects and greater precision control.It’s the feet that make the difference. Indeed, if there’s any feature that typifies the entry-level nature of the G703, I think it’s the feet. Most people don’t give much thought to what’s under the mouse, but it can be just as important as the weight, the balance, the sensor, etc. Compare the bottoms of the G703 and G903 here: IDG / Hayden Dingman We've simplified the name of this mouse from Logitech G703 LIGHTSPEED Wireless Gaming Mouse with HERO Sensor to Logitech G703 LIGHTSPEED with HERO Sensor.
