Logitech G703 Lightspeed: Two-minute review
The G703 Lightspeed is a wireless gaming mouse with a thick body and an offset sloping design that aims to improve ergonomics.
It looks more understated than your typical gaming peripheral, adopting Logitech’s muted aesthetic, with just enough concessions made to the gaming crowd thanks to its sleek form and RGB lighting (although this is relatively subtle, confined to the small Logitech G logo and a thin bar along the scroll wheel).
The G703 Lightspeed also stays true to the brand’s high build quality standards. The chassis and button materials feel premium to the touch, as do the rubberized side grips, which have a smoother texture than most and mercifully don’t collect as much detritus as others. The overall construction is solid and matches that of the best gaming mouse offerings.
Underneath you’ll find a small compartment with a magnetic lid. Numerous Logitech mice have such a compartment to store USB wireless dongles, but here it’s used to house the optional weight included in the box, which adds 10g to the 95g default. This stock weight is quite heavy compared to its rivals, but the G703 Lightspeed does an admirable job of hiding this heft thanks to the even distribution.
Another nice touch is the USB cable with its trident design, featuring two extra prongs either side of the jack for added security. Indeed, I found this to be the case when using the G703 Lightspeed in wired mode. The cable itself isn’t braided, but it’s still very thin and light, so I didn’t experience any drag.
The G703 Lightspeed can be customized using Logitech’s G HUB software. You’ll find a generous selection of button mapping options here, with plenty of common shortcuts alongside more obscure system functions available for assignment, such cycling audio input and output devices.
G HUB also lets you assign keyboard keys and macros, as well as customize the RGB lighting. However, you won’t find the more advanced tweaks present in pro-level gaming mice software, such as slam click filters or angle snapping. The most you can alter on the performance front are the DPI sensitivities for cycling (from 100 to 25,600) and the polling rate, which has a 1K maximum.
When gaming, the G703 Lightspeed acquits itself reasonably well. The mouse buttons are quite snappy, although they rebound a little slower than I would’ve liked. What’s more, the rightward slope of the body made it harder for me to tap the buttons quickly, as I couldn’t push them downwards as directly as usual.
The bulging front right side also gave me grief, as it resulted in an unnatural middle finger placement that led to discomfort after only a short while. The G703 Lightspeed isn’t a mouse you can hold loosely; it’s at its best when you envelope your entire palm around it and grip tightly on the sides. This makes controlling the G703 Lightspeed much easier, but if you’re not a fan of this grip style, then the G703 Lightspeed might not be for you.
The other buttons perform well enough: I appreciated the large side buttons, which makes them easy to use, and they provide extremely snappy actuation too. However, the scroll wheel is a little too eager, as I occasionally flicked it accidentally when pressing middle click.
I experienced no connectivity issues, with the G703 Lightspeed performing flawlessly via the 2.4GHz Lightspeed dongle. Battery life is fine, although it’s not the best, dropping about 15% after several days of use, which seems roughly in line with the quoted 35-hour lifespan (although Logitech claims it can last up to 60 hours with the RGB turned off).
The G703 Lightspeed costs $99.99 / £94.99 / AU$199.95, although you can usually find it for cheaper than that if you shop around. Still, it’s a fair price for a wireless gaming mouse with a rechargeable battery. However, it’s the same price as the Razer DeathAdder V3 Hyperspeed, which boasts a much better battery life, as well as a much lighter weight.
There’s also the Cooler Master MM311, which is considerably cheaper and the best budget gaming mouse to our mind, thanks to its smooth and fast performance. With competition like this, the various foibles of the G703 Lightspeed make it harder to recommend over its rivals.
Logitech G703 Lightspeed: Price & availability
- $99.99 / £94.99 / AU$199.95
- Available now in black
- Middle of the market
The G703 Lightspeed costs $99.99 / £94.99 / AU$199.95 and is available now in one colorway: black. It comes with a USB cable and a wireless Lightspeed USB dongle with an extension adapter. There’s also an optional insertable 10g weight, although this has to be removed if you want compatibility with Logitech’s Powerplay wireless charging mats.
For a wireless gaming mouse, it sits somewhere in the middle of the market – and Logitech’s lineup. It’s the same price as the Razer DeathAdder V3 Hyperspeed, which lasts much longer than the G703 Lightspeed on a single charge, is much lighter, and can be upgraded to have an 8K polling rate.
There are also some great picks that are even cheaper than the G703 Lightspeed. If you want something seriously light on your wallet, the Cooler Master MM311 is one of the best on this front, offering capable performance for a fraction of the price of many wireless gaming mice. Again, though, It requires an AA battery.
Logitech G703 Lightspeed: Specs
Should I buy the Logitech G703 Lightspeed?
Buy it if...
You want to grip your mouse fully
I found that the G703 Lightspeed performs best when engulfed in your palm, providing a more secure grip, easier swiping, and easier clicking.
You want a well-made gaming mouse
The G703 Lightspeed is up to the usual Logitech standards, which is to say it’s solid and premium feeling all-round.
Don't buy it if...
You want a conventional shape
Logitech has tried to make the G703 Lightspeed more ergonomic with its side slant, but I couldn’t get along with this, nor the bulbous front right side.
You want something lightweight
At 95g, the G703 Lightspeed is far from the lightest gaming mouse around, although some may prefer heavier pointers, as evinced by the included optional 10g weight.
Logitech G703 Lightspeed: Also consider
Razer DeathAdder V3 Hyperspeed
For the same list price as the G703 Lightspeed, you could also get the DeathAdder V3 Hyperspeed. This mouse is lighter and smaller, so may be a better pick for those with smaller hands. It also has a rechargeable battery like the G703 Lightspeed, but with a much longer battery life at a claimed 100 hours. What's more, its polling rate can be boosted all the way up to 8K, although you need to purchase an optional dongle.
Cooler Master MM311
The MM311 has been the undisputed king of budget wireless gaming mice for a while, thanks to its excellent performance at an ultra-low price. It does require an AA battery as well, but considering just how cheap it is, we’re happy with this sacrifice. Read our Cooler Master MM311 review.
How I tested the Logitech G703 Lightspeed
- Tested for several days
- Played various games
- Plentiful PC gaming experience
I tested the G703 Lightspeed for several days, during which time I used it for gaming, productivity, and general browsing.
I played Counter-Strike 2, a good litmus test for peripherals, as it requires quick and accurate movements and aiming. I also played S.T.A.L.K.E.R. 2: Heart of Chornobyl, which similarly requires precision.
I have been PC gaming for over a decade, and during that time I have experienced a large number of mice, reviewing numerous models in the process, including those made by Logitech.
