So how does it all work? In a word, seamlessly. When the G703 was released, Logitech renamed its wireless transmission technology “Lightspeed”, and it’s still the best we’ve tested. If you want a wireless gaming mouse that replicates the responsiveness of a wired mouse today, you must have a Logitech mouse. Interestingly, while Logitech’s 12,000dpi Pixart-derived sensor was once cutting-edge, others have released higher-DPI models in the interim. Luckily, that doesn’t matter in the slightest. Mouse DPI ratings are the equivalent of megapixels in cameras: they may be trumpeted by the marketers, but they have no impact on quality once you get beyond a threshold that has long been surpassed. In part, that’s because most office users won’t want their mouse set any higher than 1600dpi, while most gamers will lose control of their games above 3,000dpi. Sure, the 18,000dpi featured on the newest wired mice sounds like it will turn you into Superman, but it’s more likely to make you feel like you have a few screws loose.

Luckily, the Logitech sensor is plenty precise and offers very low latency in tracking directional changes, which is what really counts. We experienced no squirrely mouse movements when using the G703 on the PowerPlay mat, which is still frustratingly-common in some cheaper models. This also ties back into the excellent wireless system; we’ve found that every Bluetooth mouse we’ve used loses track of the surface regularly, even Logitech’s G603, which uses the same exterior shell as the G403/G703. We would have liked it bring excellent performance to the huge market for Bluetooth mice, but ultimately it let us down. Put another way, while Bluetooth is fine for casual use, it has yet to prove itself viable for content creators that need ultra-precise control or gamers who need unflinching reflexes. The G703, on the other hand, would be perfect for either of these target markets.


One other aspect of the user experience that we need to mention is just how well PowerPlay fades into the background, never making it known that it’s constantly keeping your mouse charged. The only hint that the system is at work, other than the small white LED on the mat, is that the wireless puck gets warm when charging, which of course is something you don’t need to worry about since it’s on the bottom of the mouse. The mouse shell itself never gets warm, nor does the mat. In part this is because the PowerPlay charging rate is quite low. We found that during constant use, it just kept up when the G703’s RGB lighting was turned off, and slowly let the mouse battery drain when the RGB lighting was on. Luckily, no one uses their mouse constantly, and the PowerPlay system will make up for lost time when you take a break to watch YouTube or get up for a snack. Interestingly, the PowerPlay mat will never charge the battery to 100%; as indicated by the Logitech Gaming System software, and confirmed to us by Logitech’s technical marketing team, keeping the battery in the 85-95% charge range ensures the fewest charge cycles and therefore the longest battery lifespan. Given that the battery is not user replaceable, it’s very good to know that Logitech has given this some thought. While we went into this review assuming that it would either keep it at 100% constantly or let it run down to some very low level and then recharge it, Logitech’s approach makes sense. Maintaining a constant 100% state would mean that the battery would be constantly bumping up against its capacity limit, which puts a lot of strain on it, whereas charging from empty would keep the battery in a charging state for long periods of time. We don’t doubt that Logitech is right in determining that at the PowerPlay’s very slow charging rate, the regular short-duration charge cycles needed to keep the G703 at an 85-95% charge puts the least amount of wear and tear on the battery’s chemical structure.


In terms of gaming performance, the G703 maintains the superiority that the G403 established. The combination of instantaneous response, a comfortable grip, and the ultralight weight mean you will never be left flat-footed mid-game. The only aspect of "performance" where Logitech falls behind is in RGB lighting. The G703 and charging mat both sport a glowing Logitech "G" that can be set to a huge range of colors, or to perform rainbox cycles in sync with each other, but honestly, Logitech has to do something to catch up in terms of making the lighting really improve aesthetics.


If you’re just jumping to the end to get the Cliff’s Notes, here’s all you need to know: the G703 with PowerPlay is simply the best-performing, most advanced input device on the market. It’s fast, it’s comfortable, it’s well built, and it’s truly wireless. There are only two questions it leaves us asking: will the competition ever be able to catch up, and how will Logitech possibly top this product?

Answers may be coming soon. In terms of competition, Corsair will be rolling out a whole lineup of wireless mice based on its new Slipstream technology, but Corsair has never released a truly acclaimed mouse design, so it’s definitely playing from facing a headwind. Then there’s Logitech’s own G903, released around the same time as the G703, which features a more aggressive gamer style and a gaggle of buttons, but uses an ambidextrous layout. Our hunch is that where Logitech goes from here is to release a more button-heavy mouse with more radical styling than the G703 (starting with cooler RGB effects), while maintaining its ergonomic right-handed shape. We’d personally appreciate if a thumb rest were sculpted into the left side, but we know not everyone loves these, and Logitech may not want to alienate any current users.

With all that said, if you’re willing to budget around $175 to your mouse, which is admittedly a lot, you simply will not be let down by the G703 PowerPlay combo. As of our publication date, the Logitech G703 Wireless Gaming Mouse is available for $83 from Amazon, while the accompanying PowerPlay Charging Mat is available for $98. The two can also be purchased in a combo package for the same price ($181).
