You might be wondering why we’re taking another look at the Logitech G502 X Lightspeed, a gaming mouse originally released in 2022, here in 2025. There are a few compelling reasons. Firstly, we’re committed to providing the most comprehensive coverage of gaming mice, which means re-evaluating even established models to see how they stack up against today’s fierce competition. It’s about understanding how a seasoned favorite truly performs over time.
Secondly, while we enthusiastically reviewed its close sibling, the G502 X Plus, at launch, we believe the G502 X Lightspeed is the superior choice within the series. It shares almost all the same fantastic qualities but omits the RGB lighting, shaves off about 4 grams of weight, offers slightly better battery life, and comes at a more attractive price point.
Finally, with three years now under its belt, I was genuinely curious – having never used this specific Lightspeed model before – if it still possessed that “special” quality amidst the wave of newer, high-performance wireless mice. The answer, as you’ll find, is largely yes, though not without its nuances.
Logitech G502 X Lightspeed – Design and Features
Despite a few minor quirks, the Logitech G502 X Lightspeed offers remarkable comfort and a generous array of extra buttons. Its ergonomic design perfectly mirrors that of other G502 X mice, featuring signature curves and contours that cradle the palm comfortably. I spent hours gaming without experiencing any hand fatigue. While I’m generally not a fan of rubberized mouse surfaces, the ridged thumb rest, surprisingly, didn’t feel sticky or abrasive – though it did have a knack for collecting dust in its grooves.
The G502 X series is often recommended for larger hands, but its actual size can be a bit misleading. The wide thumb rest and the pointed end of the right mouse button make it appear larger than it is; the main body is quite streamlined and not significantly bulkier than many standard gaming mice. However, if you have genuinely small hands, you might want to consider other options. At 102 grams, it’s on the heavier side for a gaming mouse but still lighter than the G502 X Plus, and it glides smoothly across any mouse pad thanks to its PTFE feet.
Underneath, you’ll find the responsive Hero 25K sensor and a cleverly designed storage compartment for the compact USB dongle. Sliding the dongle in can be a touch tricky initially, but once secured, it won’t budge or rattle during transport. The magnetic snap closure is a nice touch, a detail often overlooked by other wireless mice, making the Lightspeed an excellent portable companion.
From an aesthetic perspective, the mouse tends to divide opinion. The sweeping thumb rest looks quite elegant, but the button layout can appear a bit cluttered. Its sharp angles and inconsistent spacing don’t necessarily form a cohesive visual design – but taste is subjective, after all.
One of its standout selling points is the abundance of extra buttons, offering more than most high-end wireless mice not specifically designed for MMOs (like the Corsair Scimitar). You get three thumb buttons on the side and two additional buttons conveniently located next to the left-click. By default, these control your DPI settings, but they are fully customizable. More buttons translate directly to greater control and can genuinely enhance your in-game performance, especially if you, like me, find your keyboard hand getting overwhelmed during intense moments.
The third thumb button functions as a “DPI shift” by default, allowing you to temporarily lower sensitivity for precision tasks. Historically known as “sniper” buttons, modern shooters often allow separate sensitivity adjustments, so I found it more useful as an extra programmable button. What’s more, this button is detachable and can be rotated 180 degrees to better suit your grip, or you can replace it entirely with a provided blank cap. It’s a neat customization feature, though I personally found the default orientation to be the most comfortable.
Every button on the Lightspeed proved to be reliable, registering clicks instantly. The primary left and right mouse buttons utilize a hybrid mechanical-optical switch, designed to eliminate the double-clicking issues that plagued earlier 502 models. While they demand a slightly firmer press than some other mice I’ve tested, rapid clicking remains effortless. However, they do produce a somewhat cheap, springy, and echoey sound, often ending with a noticeable high-pitched ping. And if I’m being particular, all the buttons exhibit a slight wiggle when force is applied; for instance, the main buttons can sway sideways with minimal effort and even lift upwards with a gentle press. This gives the impression of a slightly less premium build for a high-end mouse. Yet, importantly, I haven’t come across reports of long-term button failures from Lightspeed users, suggesting these are minor aesthetic rather than functional concerns.
My main ergonomic concern arises when using a palm grip, where the hand is shifted forward and the palm rests fully on the mouse’s base. In this position, two of the buttons become difficult to reach: one thumb button is too far back, and one of the top buttons requires an awkward finger stretch. Those with slightly smaller hands or shorter fingers might not encounter this issue, but my hands are only marginally larger than average for men. If you typically favor a palm grip, this is something to be aware of. Fingertip and claw grips, however, felt excellent. Despite these accessibility challenges, the palm grip remained the most comfortable overall, so I used it whenever the extra thumb buttons weren’t crucial.
“Its tried and true design still makes it a solid choice for those wanting to bridge the gap between gaming performance and ergonomic upside.”
The scroll wheel is the final element that could use improvement. The inclusion of a dedicated button to switch between free-spinning and incremental scrolling is a rare and welcome feature. However, the wheel’s regular, ratcheted mode feels subpar – it’s too loud and overly stiff. While not a deal-breaker for the Lightspeed, when combined with the other minor build quality observations, it collectively contributes to a slightly less premium feel than expected from a top-tier mouse, despite its fundamental comfort and functionality.
Logitech G502 X Lightspeed – Battery Life and Software
When it comes to battery life, few mice can compete. Logitech claims up to 140 hours at its standard 1000Hz polling rate, which is an impressive 10 hours more than the G502 X Plus. My testing confirmed these figures, consistently achieving around 140-150 hours on a single charge. This is truly exceptional for a high-end wireless gaming mouse. Even with daily use for both work and gaming, you’ll easily go several weeks between charges. It’s fantastic to see how far wireless mouse battery technology, especially from Logitech, has come.
Unfortunately, the accompanying software, Logitech G Hub, is a significant drawback. While it handles sensitivity adjustments perfectly – allowing you to effortlessly tweak and cycle through DPI levels with the mouse’s dedicated buttons, and even set game-specific DPI profiles – its functionality beyond this is often frustrating. Numerous online forums are filled with complaints about G Hub’s issues, and I can add my own experience: attempting to set custom keybinds in G Hub profiles for games like Fortnite resulted in chaos. One side button suddenly made my character walk right, another opened my inventory. I quickly resorted to resetting to default and remapping buttons directly within the game.

Logitech G502 X Lightspeed – Performance and Gaming
The core requirements for an excellent wireless gaming mouse are comfort, outstanding battery life, and precise responsiveness during gameplay. The G502 X Lightspeed confidently ticks all these boxes. I put the mouse through its paces in various titles, from the rapid flick-shots of Fortnite to the deliberate click-and-drag mechanics of tactics games like Doorkickers 2.
Logitech’s wireless technology and sensors have a long-standing reputation for excellence, and even though the Hero 25K sensor has seen newer iterations, the Lightspeed consistently delivered instant responses to my clicks and accurately translated my hand movements. I experienced no latency spikes, no discernible jittering, and absolutely no unwanted phantom movements.
I prioritize using mouse controls as much as possible to free up my left hand for WASD movement and other essential commands, and the Lightspeed excels in this regard. In Fortnite, for instance, I assigned the three side buttons and one top button to my inventory slots, allowing for faster weapon switching. For Counter-Strike 2, I mapped them to grenades, and in Rematch, I used the side buttons for all three types of lob passes. In each case, I felt a genuine improvement in my gameplay.
Its standard 1000Hz polling rate is admittedly being surpassed by competitors, with many newer wireless gaming mice now offering 2000Hz, 4000Hz, or even 8000Hz, including models like the Razer Deathadder V4 Pro which I reviewed recently. However, for most users, polling rates above 1000Hz offer a negligible difference. Often, your monitor’s refresh rate or your game’s frames per second are the true limiting factors in performance, and excessively high polling rates can sometimes even strain your CPU, potentially lowering your FPS in certain games. Unless you’re a professional esports player with a top-tier rig (144Hz monitor minimum, ideally 240Hz, and a powerful CPU), you’ll find that 1000Hz is more than sufficient, and the benefits of 4000Hz are typically marginal.
It’s important to acknowledge that at its original retail price, the G502 X Lightspeed faces tougher competition now than when it launched. Newer mice with superior specifications, such as the Asus ROG Keris II Ace with its 4000Hz wireless polling rate (albeit with fewer buttons) and the excellent Deathadder V4 Pro, are available at similar price points, particularly in the US.
Verdict
The Logitech G502 X Lightspeed remains a comfortable, responsive mouse with superb battery life and plenty of programmable buttons, but it doesn’t feel quite as premium as it once did. Its tried and true design still makes it a solid choice for those wanting to bridge the gap between gaming performance and ergonomic upside, but the field has gotten much more competitive. However, until Logitech puts out a true successor, you can’t go wrong with the G502 X Lightspeed, especially when you can often find it at a decent discount.
