Logitech G703 Review

Logitech G703 specs

Alternatives

If you want a lighter gaming mouse: The Razer DeathAdder V3 Pro is featherlight at 63 grams. It also retains an ergonomic shape and has S-tier performance. But that performance will cost you much more.

If you want a smaller gaming mouse: The Glorious Model D uses a similar ergonomic design language but is made for smaller hands and weighs significantly less.

If you want a symmetrical design: The Logitech G Pro Wireless includes most of the same specs under the hood and has a similar price tag. It is designed differently with a symmetrical shape that some gamers prefer.

Performance

Weight

The Logitech G703 mouse, also known as the Logitech G703 Lightspeed and Logitech G703 Hero, won’t win a podium spot as the lightest gaming mouse at a minimum weight of 92 grams. But it has a trick up its sleeve. The G703’s weight can be tuned to 102 grams using the additional puck-shaped weight in the box.

Just add the weight by popping open the magnetic bottom cover and slotting in the weight.

At its max weight of 102 grams, this is beefy compared to the vast array of six-button gaming mice popular with FPS gamers. Not every gamer prefers an ultralight gaming mouse, and that’s the market for the G703. The Glorious Model D and Razer DeathAdder V3 Pro are upgrades if you want a similar shape but a lighter weight.

Sensor

Most of the best Logitech gaming mice, including the G703, use Logitech’s Hero 25K sensor, which has a wide DPI range of 100 to 25,600. The Hero 25K sensor is one of the best sensors on the market, and it is fast and precise with excellent tracking.

While most gamers will not come close to maxing out the 25,600 DPI, there’s comfort in knowing the sensor tracks accurately at 400 inches per second, plenty fast enough for the quickest mouse flicks and on par with the best gaming mice.

Polling rate

The Logitech G703 wireless gaming mouse has a 1000 Hz max polling rate that you can set to 125 Hz, 250 Hz, or 500 Hz in G-Hub. But it’s good to stick with the highest polling rate if you want the best latency performance.

This way, your mouse reports inputs back to your computer 1,000 times per second versus less frequently, which increases latency.

Some gaming mice have higher max polling rates if you want to squeeze every possible latency advantage out of your mouse. Consider the Razer Viper 8K Hz if wanting a max 8,000 Hz polling rate. Razer’s best gaming mice also pair with its after-market HyperPolling dongle, which increases the max polling rate from 1000 Hz to 4000 Hz.

Button performance and sound

One potential letdown of the Logitech G703 is the feel of the Omron mechanical switch in the L/R buttons. The clicks aren’t crisp and don’t have much tactile feedback. That’s the same story for many Logitech models, though. Once using any mouse as your daily driver for a long enough time, it likely won’t be an issue.

On a more positive note, the Logitech G703’s switches are rated for 50 million clicks, which is good for its price tag.

Gliding

The Logitech G703 glides well enough on a mousepad but isn’t buttery smooth. The gliding experience is primarily due to the higher weight than other FPS gaming mice. The G703 uses a similar layout for its PTFE feet as the Logitech G Pro Wireless, but the latter glides much smoother with its lower weight.

Connectivity

Wireless connection

The Logitech G703 runs on a standard 2.4 Ghz USB receiver plugged into your computer. As with most fast gaming mice, there’s no Bluetooth due to the latency disadvantage of the slower transmission protocol.

While all fast mice rely on the 2.4 GHz transmission standard, Logitech layers in additional tuning with its branded Lightspeed wireless technology, which improves latency.

The G703 also includes a USB extender to improve performance by moving the USB receiver closer to your mouse. We haven’t tested the latency performance difference between using the extender or not, though it’s likely fractions of a millisecond. But an improvement is an improvement, however minor, when the fastest trigger finger secures the W.

There is no onboard USB storage since the weight tuning system takes up space that would otherwise be dedicated to a slot to store the USB receiver.

Battery life

The G703’s battery life is passable at 60 hours of advertised battery life. Expect real-world battery life to be lower with RGB enabled and using the max polling rate.

However, battery life may not be an issue if pairing the G703 with Logitech’s wireless PowerPlay charging mat that constantly charges your mouse while gaming.

If you’re looking for a similarly-shaped mouse with better battery life, the Pulsar Xlite V2 has 70 hours of advertised battery life. The Razer DeathAdder V3 Pro trounces both with 90 hours of advertised battery life.

Charging cable

One other gripe with the Logitech G703 is the charging cable quality. Including a stiff, rubbery charging cable is a headscratcher at this price point. But consider that Logitech’s more expensive flagship models fall into the same trap.

A flexible paracord charging cable feels more premium and is easier to store. Plus, paracord cables are cheap, and many budget gaming mice at a fraction of the price have far better cables.

I’m also not a fan of Logitech’s proprietary micro-USB port. It’s designed to stay connected and will likely do so even if helicoptering the G703 and cable over your head like a madman. But plugging in and removing the connector isn’t smooth, and it feels like the connector is over-designed and should just be USB-C.

Design

Buttons

The Logitech G703 uses a standard six-button layout typical for performance-oriented gaming mice. You won’t be running raids in World of Warcraft with tons of buttons at your disposal since there isn’t a massive side array of buttons. However, there is a solid number of total programmable actions: You can map 11 total inputs using Logitech’s G-Shift functionality.

The L/R buttons are slightly scalloped and flair outwards to help your fingers find the center of the button. One design cue we wish more gaming mice would copy is the size of the side buttons, which are impossible to miss and are well-positioned.

Scroll wheel

The scroll wheel on the G703 is excellent. The steps are tactile and not clunky. The rubberized material surrounds the wheel, giving you precise scrolling control. The scroll wheel click is also well-balanced without requiring much downforce.

There is no free-scroll or L/R tilt functionality, as is common with competing gaming mice.

Shape

Ergonomic gaming mice can go in two different directions with the design: subtle curves for a balanced experience or a full-on ergonomic design with a thumb rest, right finger rest, and a steep slant.

The Logitech G703 goes with the former, safer approach. The subtle ergonomic shape cups your hand well in a natural position, unlike a symmetrical gaming mouse, which requires you to orient your hand flat.

The slightly taller-than-average height also makes the G703 feel large.

Hand size and grip style

The Logitech G703 fits most medium and large hands. It’s a beefier gaming mouse compared to many lower-profile models and is not fit for small hands. The Glorious Model D- is a solid alternative that retains a similar ergonomic shape in a smaller chassis.

We already discussed how the Logitech G703 plays it safe with the shape, so it’s easy to recommend for palm, claw, and fingertip grips. The top hump provides excellent palm support and molds nicely to your hand when cupped.

Logitech designed the G703 wanting it to work with claw and fingertip grips as well. The inward side recesses include a grippy material that ensures you don’t lose control of the mouse when using claw and fingertip grips. The grippy material is beneficial when your hand is stationary and you’re moving the mouse with only your fingers, such as when making micro adjustments when aiming in first-person shooters.

Customization and software

RGB

There are two RGB zones in the G703, one that controls the logo lighting on the back and the other in the scroll wheel. G-Hub offers a wide array of RGB customization options, giving you free rein to deck out the G703 to your liking.

Profiles

You can carry onboard up to five profiles configured in G-Hub, helpful if you play different roles in certain games or want versatility in productivity-related tasks.

You can also set custom profiles by program so the Logitech G703 automatically switches profiles based on the windowed program.

If seamlessly switching onboard profiles is important, remap the button behind the scroll wheel to a profile-changing command.

G-Hub software

Logitech’s companion G-Hub software is where you manage all your Logitech gaming peripherals. G-Hub is one of the most feature-rich software programs with a simple UI that makes configuring your new gaming mouse easy. You can do the following with your G703 in G-Hub.

• Remap your mouse buttons and enable G-Shift for an added layer of customization
• Adjust the DPI presets in increments of 50 from 100 to 25,600
• Adjust the polling rate from a list including 125 Hz, 250 Hz, 500 Hz, and 1000 Hz presets
• Customize the RGB effects
• Set custom configurations to automatically change profiles when opening specific games

Rare for gaming mice, Logitech also offers full software compatibility in macOS. Most other manufacturer software programs are only compatible with Windows.
