The G403 is one of Logitech’s most popular gaming mice, garnering a lot of praise from casual gamers. But what makes it so great?

The Logitech G403 offers a pleasant ergonomic form and some impressive characteristics and functions. For a fraction of the cost, get a professional mouse!

Logitech provides gamers with a wide range of mice in various sizes and styles. In 2016, Logitech introduced the new Prodigy line, which included the G403 ergonomic gaming mouse, not a remix of twisted fire starter. The goal of the series was to appeal to the casual gamer by providing tournament-ready mice at a lower price point. As a result, Logitech designed the G403 with a safe and ergonomic form in mind and some high-end features.

The G403 is a basic mouse with gentle slopes, and curves that you can tell will be pleasant to hold simply by looking at it. It has a comfortable grip and a PMW3366 sensor, which is still rated as one of the best on the market. So for under £40/$40, you get a high-performance mouse with an ergonomic design for comfort.

Size & Weight

Logitech G403 Product Right Side

The G403 is a medium-sized mouse that anybody may use with a right hand. It’s a giant mouse, but because of its design, it doesn’t feel as significant in the hand as some others. The mouse is 12.4 cm long, over a centimeter longer than the G302. Despite the fact that the mice are longer, the G403 has a broader body (6.9 cm) and a higher height (4.3 cm), making it closer in size to the SteelSeries Rival 600. The mouse is comfortable to handle and can be used with any grip, however if you have larger hands and use a palm grip, your fingers may pop over the edge a little. Check our hand-size chart to determine whether the G403 is suitable with your hand size. The mouse is 4.3 cm tall, similar to the Razer Mamba and somewhat larger than the HyperX Pulsefire FPS Pro. When compared to the FPS Pro, it’s much more pleasant to handle since it’s somewhat broader on the surface.

As a result, the G403’s size may appeal to a broad audience, and its weight is commensurate. This mouse is very light, weighing just 2 grams more than the G Pro Wired. Swiping feels light, yet because to its substantial bulk, you never feel like you’re losing control. It’s so light that the friction from the extra thick wire it comes with is noticeable, but I’ll get into that later. The weight may be adjusted; the G403 comes with a 10g additional weight that can be inserted into the Logitech puck on the mouse’s bottom.

Shape & Texture

Logitech G403 Product Angle 2

The form of the G403 is safe and straightforward, yet it manages to be lovely. It has an angular form with delicate gentle curves that develop into finger grooves. It has a similar design to the Deathadder in terms of ergonomics, but they don’t feel the same to grip. The mouse’s curvature is lovely and progressive, giving it a bow form from the side, similar to the new G Pro Wireless. The front of the mouse flattens out, providing your fingertips a comfortable area to rest, while the rear slopes out for a more secure grasp. The thumb groove seems to have been thoroughly thought out and is really pleasant to hold. The right-hand side slopes strongly, which I appreciate since my ring and pinky fingers naturally wrap around the mouse. The overall design is comfortable, simple to hold, and gives the impression that the mouse is an extension of my hand.

On the G403, Logitech continues to apply the specialized coating. It’s a matte black smooth plastic that’s considerably simpler to clean than other manufacturers’ soft-touch materials. Because of the ergonomic design, the smooth plastic does not impede grip, but it is slick to the touch. I don’t have the most sweaty hands, but the material appears to handle moisture well, and I never lost control. If your hands become wet, don’t worry: the G403’s sides contain a rubberized substance that seems like a soft-touch finish, providing you all the grip you need.

To do this, the G403 features Omron-developed switches that may last up to 20 million clicks, have a low actuation, and are situated just under the principal buttons. The Primary buttons are distinct from the rest of the mouse shell, which I appreciate, and when pushed, they make a pleasant audible click. The shape of the buttons enables your fingertips to rest on them without mistakenly pushing them all of the time.

The mouse has a wheel in its usual location that you may program if desired. The scrolling wheel is haptic, with a low volume sound and a deep audible click noise. It isn’t the most elegant scroll wheel, but it works and is responsive. The DPI button is located behind the wheel, and it allows you to modify sensitivity on the fly while playing. The DPI button is hidden away in its own groove, so it won’t be accidently pressed by your index or middle fingers.

On the G403, there are six customizable buttons, two of which are on the side for your thumb. The side buttons look to be huge and clumsy, but they are really quite sensitive and have Omron switches behind them, so you’re getting some amazing side buttons. They’re simple to reach with my thumb, and I don’t have to change my grip to do so. I can easily slide my thumb up to activate them without unintentionally pressing them all the time.


The cable on the G403 is 2.1 meters long. It’s braided for more safety, however the braiding has a rough feel that makes it more prone to snag on your desk or peripherals. A bungee can be used to minimize snagging, but the wire is one of the heaviest I’ve ever had in a mouse, and you can feel it. Even with a bungee, the cord produces a horrible noise when it scrapes against my XXL QcK pad, which I can’t prevent since I prefer a little slack from my wire (use low sensitivity). With my headset on, I couldn’t hear the scraping, and I’d become used to the cable’s weight, so it’s not a huge problem given the mouse’s small weight. It’s a thick wire that has to be stuffed into the bungee, but it fits in every Bungee I have without sliding, which is a first. Logitech is the best at making sure the mouse is ready to use right out of the box; they wrap the cord around the square casing to protect it from bending.

Sensor & Performance

Logitech G403 Product Bottom

The PWM3366 optical sensor, which is an all-around outstanding sensor, was used by Logitech in the G403. It was a joy to use; the sensor was delightfully smooth, and no matter how little or massive my motions were, the sensor stayed steady and didn’t let me down. It has a DPI range of 200 to 12,000, which you may adjust in the program. During testing, I didn’t observe any jitter, and the sensor stayed exact without latency. The G403 has a polling rate of 1000Hz, which makes it as responsive as a gaming mouse should be.

This sensor allows for seamless gaming, and when combined with the excellent ergonomic profile, you get a comfortable mouse that can operate on any surface. I tend to use my mice at approximately 800 DPI, and 12,000 is obviously too high, but I was able to see how accurate and reliable the sensor was when I tried it at 3200 DPI. The form was beautiful, and it made a difference in terms of aiming in-game, as I found this mouse to be quite simple to adjust to. I never lost control when playing or browsing because of the textured sides. The G403 functioned well in all of my games, but the mouse’s most tremendous potential lies in FPS games, owing to its precise sensor and ergonomic design.


The G-hub software from Logitech is fantastic; it’s user-friendly and responsive, and I don’t have to log in! The G403 now has Logitech’s Lighsync technology, and the G-Hub software allows you to alter the colors. Although the DPI may be changed in the software, it is already preprogrammed and recorded in the onboard memory. You may now use the DPI button to alter the DPI without going into the program again. Because this mouse lacks a profile button, switching profiles requires going into the software, as I don’t believe the others can be programmed to do so. The polling rate may be changed from 125 Hz to 1000 Hz.


Logitech has succeeded in providing a professional mouse to casual and amateur players. The G403 features a well-designed form that stays comfortable even after long gaming periods, which is always a bonus. Despite its superb characteristics, the sensor remains a fantastic choice for everyone. With the mouse now available for under £40/$40, you can obtain a high-performance mouse that significantly enhances your aim and gaming. It’s a great deal with many features, so have a look!
