The Logitech G703 LIGHTSPEED is a great wireless gaming mouse. It's well-built and has a comfortable shape that suits most grips and hand sizes. Click latency is also extremely low, whether you play wired or wirelessly through its USB receiver. Its HERO 16k sensor provides exceptional performance, with a wide CPI range, short lift-off distance, and high polling rate. The buttons are clicky and satisfying, and they're all programmable via G HUB, where you can also adjust performance settings and customize the RGB lighting. While the scroll wheel feels sturdy, it doesn't support tilt inputs, and you can't unlock to scroll through long documents quickly. On the upside, it's fully compatible with Windows and macOS, and it has on-board memory to store profiles.
Update 09/29/2020: Logitech has released a firmware update (version 22.2.15) that increases the HERO sensor's CPI range. It can now go up to 25,600 CPI.
Our Verdict
The Logitech G703 is a great mouse for office use. It's a well-built mouse with a comfortable shape to use for long hours. It has a total of six buttons, all of which are programmable. Unfortunately, while its wireless connection allows you to keep your setup clean, it needs a wireless USB receiver since it doesn't have Bluetooth capability. Also, the scroll wheel can't tilt for side-scrolling, and you can't unlock it for infinite scrolling.

The Logitech G703 is excellent for playing MMO games. It has a good number of buttons, all of which are macro-programmable through G HUB, but it won't give as many as dedicated MMO mice. It's very comfortable to use and shouldn't cause fatigue during those hours-long raids. It has a wide CPI range, and you can adjust the CPI setting in small increments to get it exactly to your liking.

The Logitech G703 is very good for ultra-light gaming. It's wireless, lightweight, and you can make it even lighter by removing the plastic cover on the underside. However, it's not quite as light as some other options with a honeycomb pattern or other dedicated ultra-light mice. On the upside, it has low click latency to make every action feel instantaneous, and its high polling rate makes your movements feel smooth.

Test Results
The Logitech G703 LIGHTSPEED has a sleek design and looks nearly identical to the Logitech G403 Wireless Gaming Mouse. It has a matte finish that feels soft to the touch, and the rubber grips on the sides blend in well with the rest of the mouse. The logo and the scroll wheel have RGB lighting built-in, which you can customize via software. The lighting is visible even in a well-lit room. It isn't too heavy on the gamer aesthetic, so it shouldn't look out of place in a work environment. If you're interested in a mouse with a similar design language and shape but without RGB lighting, check out the Vaxee OUTSET AX.
Even though the Logitech G703 is a wireless mouse, it's on the bulky side, and there's no compartment to store the USB receiver, making it less ideal for portable use.
The Logitech G703 is a fairly light mouse, suitable for FPS games, but isn't quite as light as some other options like the Glorious Model O or even the Razer Viper Ultimate. You can also make it heavier by adding the included 10g weight, which is kept in place by a plastic, magnetic cover on the mouse's underside. If you want the mouse to be lighter, you can remove the cover entirely, shedding another 3g.
The build quality is excellent and identical to the wired Logitech G403 HERO. It's all plastic, but everything feels solid and sturdy. The buttons are clicky and satisfying, and the sides are nice and grippy. The feet are good quality and allow the mouse to slide around smoothly.
The Logitech G703 is very comfortable and shouldn't cause any fatigue. It's slightly slanted and designed for right-handed use. The side buttons are well-placed, as they're high enough that you won't trigger them accidentally but still close enough to reach comfortably. They're also big and easy to differentiate by feel. The mouse is on the bulky side, and it has a fairly big hump that makes it less ideal for those with small hands and using a fingertip grip.
The Logitech G703 is suitable for a palm grip regardless of hand size.
Due to the mouse's fairly big hump, it can be difficult for those with small hands to reach the scroll wheel and click the buttons when using a claw grip.
The Logitech G703 isn't ideal for a fingertip grip unless you have large hands, as the buttons and scroll wheel are hard to reach for smaller hands.
The Logitech G703 can only connect wirelessly using the included USB receiver since it doesn't have Bluetooth capability. It has a built-in rechargeable battery, and it's usable while charging. The battery is rated to last up to 35 hours with the RGB lighting on and 60 hours with it off; however, we don't test battery life. If you're interested in a wireless gaming mouse with Bluetooth support, check out the ASUS ROG Keris Wireless.
The cable is braided and of good quality. It's flexible and doesn't keep any kinks. Although the connector looks proprietary, it's just a regular micro-USB connector, so you can use any cable that you like. If your desktop computer is placed far enough to affect performance, a receiver extension adapter allows you to place the receiver closer to you. When the mouse is plugged in, data is sent via the wired connection, not wirelessly.

Update 10/07/2020: We increased the total number of programmable inputs by one. We incorrectly listed that you can't reprogram the left button without assigning the left click action to another button, but you can reprogram the button.
You can switch profile and CPI setting directly on the mouse, and all the buttons are programmable through G HUB. The mouse has two side buttons on the left side, which might not be enough for more serious MMO players. If you're interested in a similar wireless gaming mouse that has hot-swappable left and right click switches, check out the ASUS ROG Strix Impact II Wireless.
The mouse wheel is incremented, but unfortunately, you can't unlock it for infinite scrolling like some other office-oriented Logitech mice, and it also doesn't support tilt inputs.
The click latency is extremely low, and most people shouldn't notice any delay when using this mouse wirelessly or wired.
The Logitech G703 has superb software support. Logitech's G HUB lets you customize the two RGB lighting zones, remap buttons, program macros, and adjust performance settings. There's on-board memory to save your profiles, so you can access them on a computer that doesn't have G HUB installed.
Differences Between Sizes And Variants
There are two versions of the Logitech G703. Although they look identical, the original version (non-HERO) has a PMW3366 sensor with an advertised 200 to 12,000 CPI range, while the HERO version that we reviewed has a 100 to 16,000 CPI range. We reviewed the HERO version, and don't expect our review to be valid for the older model.
Compared To Other Mice
The Logitech G703 LIGHTSPEED is a great overall gaming mouse and seems to be a nice upgrade over the previous model thanks to the latest sensor, although we didn't test the older one. However, if you want a wireless Logitech mouse with more side buttons for MMO gaming, you can also look at the Logitech G604 Lightspeed, although it's a bit more expensive. For a wired-only option, take a look at the Logitech G403 HERO. For more options, check out our recommendations for the best wireless gaming mouse, the best FPS mouse, and the best gaming mouse.
The Logitech G PRO X SUPERLIGHT and the Logitech G703 LIGHTSPEED Wireless Gaming Mouse with HERO Sensor are excellent wireless gaming mice.
