Logitech G Pro X Superlight 2 DEX Review

Overview

The Logitech G Pro X Superlight 2 DEX is what happens when Logitech takes the most influential esports mouse of the modern era and finally gives it a shape with opinions. Launched in September 2024 at $159.99, the DEX carries over the entire Superlight 2 recipe — the HERO 2 sensor, LIGHTFORCE hybrid switches, 8,000 Hz LIGHTSPEED wireless, a 60-gram chassis, and a 95-hour battery — and wraps it in an asymmetrical, right-handed shell sculpted in collaboration with pros from NAVI, G2, TSM, Astralis, FlyQuest, and RED. If you've ever wanted Superlight 2 performance but wished the ambidextrous slab filled your palm a little more, this is the mouse Logitech built for you.

The name stands for dexterity, and the design brief is straightforward: the Superlight 2's flat, symmetrical shape is the safe choice that works for nearly everyone, while the DEX trades that universality for a more supportive, contoured fit aimed squarely at right-handed palm and claw grippers. It's the same play Razer made with the DeathAdder V3 Pro and V4 Pro — and at almost identical dimensions (125.8 x 67.7 x 43.9 mm, within a hair of the DeathAdder V3 Pro), the DEX is explicitly gunning for that throne.

The catch is that the shape is the product. Internally, there is nothing here you haven't already read in our Superlight 2 review; externally, the DEX is one of the most divisive flagship shapes of the last few years. Press verdicts on the shell range from "the gaming mouse to beat" to a blunt "hard to handle," and community feedback splits the same way: owners either describe it as the most comfortable mouse they've ever used or as an awkward fit they never adjusted to. This review is about which side you're likely to land on — and what to inspect before committing $160.

Build Quality and Design

The DEX is a 60-gram mouse that RTINGS' scale measured at 58.4 g — marginally under spec, and remarkable for a shell that is noticeably larger than the Superlight 2's. Logitech pulls it off with a thin-but-stiff polycarbonate chassis; there are no honeycomb cutouts and no creaks in normal use, though a small minority of owners report slight flex under firm grip pressure that feels out of place at this price point.

The shape is the headline. The hump is shifted toward the center-left and sits higher than the Superlight 2's, with a wider rear end that cups the palm, a pronounced thumb groove on the left, and a gentler slope on the right for the ring and pinky fingers. Multiple community impressions describe it as a cross between the classic G403 and the Superlight 2 — familiar G403-style arch support up top with the SL2's cleaner right side for claw grip. Compared with the Lamzu Thorn, another ergo favorite, the DEX carries a less aggressive back hump and higher main buttons. It's a medium-large shape: press testing notes it accommodates all grip types but really wants larger hands for fingertip use, and smaller hands will find the hump placement pronounced.

The coating is a matte, smooth finish that draws genuinely split opinions. Some owners compare it favorably to Lamzu's grippy coating and report no sweat issues in long sessions; others — particularly on the white model — describe it as slippery enough to justify the included grip tape. Logitech ships custom-cut grip tape for the sides and buttons in the box, which is honest about the finish's limits, and the tape solves the problem for most complainants.

Buttons are a mixed bag and the single biggest QC talking point. The LIGHTFORCE hybrid optical-mechanical main clicks are loud, crisp, and fast — press reviews consistently call them clicky and satisfying, and more than one owner calls them the best clicks they've felt on any mouse. But early production units drew repeated reports of pre-travel, button wobble, and inconsistent left/right actuation weight, alongside mushy, wobbly side buttons. The pattern across community threads is a quality lottery: some units arrive flawless, others feel like a $60 mouse wearing a $160 badge. A hand-picked display unit, notably, exhibited most of the same issues fixed, suggesting later batches tightened up — but the variance is real enough that a careful inspection on arrival is warranted.

The scroll wheel is the other weak link, and it's the one complaint that spans every source type. One major outlet flags a mushy middle click; another describes a wheel that's "just loose enough" with a rattle when flicked quickly and a stiff click; a third unit had lateral play when pressed from the side; and lab-site comment threads include owners describing the middle-click release registering early. Logitech also stuck with a mechanical wheel encoder here while Razer moved to optical encoders in the same price class — a durability decision that doesn't age well. Most units work fine out of the box, but this is the component most likely to develop issues over time.

The underside is well executed: large zero-additive PTFE skates cover the upper third of the mouse, plus a strip around the magnetic dongle door and a small ring around the sensor. A spare PTFE-covered door is included for more glide, and the magnetic door swaps out for the PowerPlay module. The skates are on the thin side, so the mouse performs best on a pad. The box also includes a 1.8 m rubber USB-C to USB-A charging cable, the 2.4 GHz dongle with a USB extender, and the grip tape. There's no RGB and no Bluetooth — just a small status LED — which is exactly right for a tournament-focused tool.

Key Features

• HERO 2 sensor: up to 44,000 DPI, 888 IPS, and 88 G acceleration — the same flagship optical sensor as the Superlight 2, with tracking accuracy that lab testing consistently ranks at the top of the wireless field.
• 8,000 Hz LIGHTSPEED wireless: up to 8 kHz polling (0.25 ms) over 2.4 GHz out of the box, dropping to 1,000 Hz when wired. Tom's Hardware measured a 0.125 ms response time and found the link stable at 1,000, 4,000, and 8,000 Hz.
• LIGHTFORCE hybrid switches: optical actuation speed with a mechanical click feel; a firmware/software toggle allows optical-only operation for maximum speed at a battery cost.
• 95-hour battery: rated at 1,000 Hz; measurements put it at roughly 19 hours at 8 kHz with optical-only actuation. USB-C charging, plus full PowerPlay and PowerPlay 2 compatibility for effectively infinite charge (the module adds about 3 g).
• Five buttons with G-Shift: two-layer remapping via G HUB; there's no dedicated DPI button on the shell, though any button can be remapped to serve as one.
• G HUB extras: per-axis X/Y DPI adjustment, three-level lift-off distance, and a sensor calibration tool that mimics the feel of another mouse you own — a genuinely useful onboarding feature.
• Zero-additive PTFE skates: large stock feet plus a spare PTFE door for the dongle compartment.

Performance

Performance is the easy part of this review, because it is, to the gram, the Superlight 2. The DEX uses the same HERO 2 sensor, the same LIGHTFORCE switches, and the same LIGHTSPEED radio as our 9/10-rated Superlight 2, and lab results track accordingly: RTINGS rates the DEX an outstanding FPS mouse with remarkably good all-around sensor performance and exceptionally low click latency, and its raw-performance verdict — exceptional click and sensor latency plus a working 8 kHz wireless mode — is the same box checked for every modern flagship.

In practical terms, the sensor's 44,000 DPI ceiling and 888 IPS tracking are far beyond what any human can outrun; the meaningful spec is latency, and here the DEX sits at the top of the wireless charts. The measured 0.125 ms response time and stable connection at every polling step confirm what the pro endorsements imply. The sensible take for most buyers is that the mouse is snappy and responsive at the default 1,000 Hz, and 8 kHz shaves off tens of nanoseconds that few players will perceive — the sweet spot for most sits between 1 kHz and 4 kHz, where you keep nearly all the responsiveness without gutting the battery.

The click feel is where opinion diverges from the spec sheet. LIGHTFORCE switches are fast, but they're also loud and tactile with a somewhat inconsistent feel — and on early units, the pre-travel and wobble reports covered above undermine the premium experience. When you get a good unit, owner feedback is emphatic: the main clicks rank among the best on any mouse, period. The balance and weight distribution also earn consistent praise — community impressions note the larger shape doesn't feel its size in hand, and the low weight makes the ergonomic shell easy to flick and reposition for fast flicks.

Battery behavior is worth knowing before you buy: 95 hours at 1,000 Hz is genuinely excellent — roughly biweekly charging in real use — but cranking to 8 kHz with optical-only switches cuts that to under a day of constant play. The PowerPlay option sidesteps the trade entirely for owners who already run Logitech's charging mat.

Pros and Cons

Pros:

• Flagship HERO 2 performance, 8 kHz wireless, and sub-millisecond latency — identical elite internals to the Superlight 2
• Genuinely ergonomic right-hand shape with real palm support; a major comfort upgrade over the flat ambidextrous SL2 for palm and claw grippers
• 60 g (58.4 g measured) with excellent weight balance — feels lighter than the larger shell suggests
• 95-hour battery at 1 kHz, USB-C charging, and PowerPlay 2 support for unlimited charge
• Excellent stock PTFE feet with a spare door, included grip tape, and a clean, no-RGB pro aesthetic
• G HUB's per-axis DPI, lift-off control, and sensor calibration are genuinely useful

Cons:

• The shape is polarizing — the pronounced center-left hump actively bothers some palm grippers and smaller hands; this is a try-before-you-buy proposition
• QC variance in early units: pre-travel and wobble in main clicks, mushy side buttons, occasional body flex
• The mechanical scroll wheel is the weakest component — mushy or late middle-click reports and lateral play across multiple reviews, plus durability concerns versus rivals' optical wheels
• $159.99 for internals identical to the $149.99 Superlight 2 — you're paying a premium for the shell
• Right-handed only; left-handed players are locked out entirely

Who Should Buy This

Buy the DEX if you're a right-handed player with medium-to-large hands who wants Superlight 2-tier performance in a shell that actually supports your palm — particularly palm and claw grippers who found the standard SL2 too flat or too narrow. It's also the pick for Logitech-ecosystem loyalists: G HUB integration, PowerPlay charging, and the same sensor tuning the pro scene runs. Competitive FPS players will find a latency floor identical to the ambidextrous SL2 with better long-session comfort.

Skip it if you're left-handed, if you have smaller hands (the hump and rear flare will fight you), if you mostly fingertip-grip, or if you need Bluetooth for multi-device work — this is a dongle-or-wired esports tool, and productivity-minded buyers should look elsewhere. Budget-conscious shoppers should note you're paying a shape premium over the identical-internals Superlight 2, and palm grippers who found the DeathAdder line's curve perfect should test the DEX's steeper center-left hump before committing.

Alternatives to Consider

• Razer DeathAdder V4 Pro ($149.99) — our 8.5/10 pick and the ergonomic king: 56 g, 8 kHz in the box, and an optical-everything build including a scroll wheel encoder that should outlast the DEX's mechanical one. The safer ergo choice if you want less shape controversy.
• Logitech G Pro X Superlight 2 ($149.99) — the same internals in the safe ambidextrous shell, rated 9.0/10 by us. Buy this if you want identical performance without the shape gamble, or if you share the mouse between hands.
• Razer Viper V3 Pro ($119.99) — 54 g, 8 kHz, RTINGS-verified top-tier latency at a lower price; our 8.9/10. The best value flagship for players who don't need ergonomic shaping.
• Pulsar X3 ($99.95) — a G403-style ergonomic shape at 52 g for roughly $60 less, reviewed 8.3/10; the budget-ergo alternative for medium hands.

Verdict

The Logitech G Pro X Superlight 2 DEX is a flagship mouse wearing a shape that will either fit you perfectly or not at all. The hardware is beyond reproach: HERO 2, 8 kHz LIGHTSPEED, LIGHTFORCE switches, a 95-hour battery, and 60 grams of balanced chassis make it one of the fastest wireless mice money can buy, and the press consensus — from a top-shelf 5/5 to PC Gamer's 84/100 — lands firmly in excellent territory. But the shell that makes it special for one owner makes it unusable for another, and the QC variance around the clicks and the mechanical scroll wheel add a lottery element that a $160 flagship shouldn't have.

Scored against what it claims to be — a right-handed esports flagship — the DEX earns 8.5/10. It's an excellent mouse for its intended audience, held back from the Superlight 2's 9.0 only by a shape that doesn't fit everyone and build-quality inconsistency that a hand-picked display unit wouldn't have. If the shape suits your hand, this is one of the best ergonomic gaming mice you can buy in 2026. If it doesn't, no spec sheet in the world will save you. Buy from a retailer with easy returns, inspect the clicks and wheel on arrival, and enjoy one of the fastest wireless mice ever made.
