Logitech Pro X Superlight 2 DEX Review: Ergonomic Excellence for Right-Handed Gamers

Introduction

Following three generations of lightweight gaming mice, Logitech G presents a radical version of its professional gaming mouse. As the first asymmetric model in its lineage, the Pro X Superlight 2 DEX caters exclusively to right-handed users.

The DEX designation derives from "dexterity" and "dexter"—Latin for right. This departure from ambidextrous design enables Logitech to optimise the mouse's morphology for superior ergonomics specifically tailored to right-handed gamers. Whilst this choice won't please everyone, the company has taken a decisive stance: attempting to accommodate all users often results in compromises that serve none particularly well.

For left-handed users or those preferring ambidextrous designs, Logitech simultaneously released the Pro 2 Lightspeed. This model maintains perfect ambidexterity with removable side buttons inherited from the G900, weighing 80 grammes—slightly heavier than the DEX but offering greater versatility with up to seven programmable buttons.

The Pro X Superlight 2 DEX represents the culmination of Logitech's pursuit of the perfect competitive gaming mouse, developed in collaboration with over 30 esports athletes from teams including NAVI, G2, TSM, Astralis, and FlyQuest RED. The question remains: does this specialist approach deliver tangible benefits?

Asymmetric Excellence: A Question of Ergonomics

DEX, dexterity, and dexter. Understanding this Superlight 2 revision requires appreciating Logitech's deliberate departure from ambidextrous design. The company has grasped the nettle: by focusing exclusively on right-handed users, they've created a mouse whose morphology adapts to superior hand placement. Attempting universal compatibility inevitably results in half-measures; Logitech has avoided this trap.

Unlike its predecessors, the Pro X Superlight 2 DEX features an asymmetric design sculpted specifically for right hands. The thumb contour follows natural anatomy, whilst the pronounced dorsal curve fills the palm without pressure or voids. The front face slopes gently rightward, respecting natural finger alignment—an approach clearly inherited from Logitech's engineering excellence on their office peripherals and previously glimpsed on models like the G502 X.

As with the G502 X and MX Master 3S, the Pro X Superlight 2 DEX's ergonomics prove perfect and extraordinarily natural. This assessment applies particularly to small and medium-sized hands; the mouse maintains compact dimensions of 125.8 × 67.7 × 43.9 mm. Those with larger hands may find the proportions restrictive.

Thanks to its minimal weight, the DEX respects its predecessors' versatility by accommodating all grip styles: Palm Grip, Claw Grip, and Fingertip. The featherweight construction permits effortless repositioning regardless of your preferred technique.

Weight Reduction Philosophy

The Pro X Superlight 2 DEX maintains the 60-gramme weight established by its immediate predecessor. Further reduction proves challenging without compromising structural integrity. Logitech's "light is right" philosophy—echoing Colin Chapman's famous engineering maxim—has driven systematic weight reduction through successive generations.

Achieving ultra-lightweight status necessitated sacrifices: removable buttons disappeared, logo backlighting vanished, and DPI indicator LEDs were eliminated. Each gramme mattered. This philosophy delivers tangible benefits: a 60-gramme mouse prevents muscular fatigue in wrist or forearm even during marathon gaming sessions—crucial for esports professionals and streamers.

However, the sensation of wielding a 60-gramme mouse proves distinctive. Some users initially perceive the mouse as floating or difficult to control precisely. An adaptation period becomes necessary, as most gamers grow accustomed to heavier peripherals. Once acclimated, the benefits become apparent: effortless movement, reduced strain, and enhanced precision during extended play sessions.

Surface Treatment and Grip Considerations

The primary ergonomic criticism concerns grip. The mouse's surface remains absolutely smooth—a consequence of weight optimisation. No texture or coating provides natural purchase. Logitech acknowledges this limitation by including a sheet of 3M grip tape for self-application.

This inclusion presents mixed feelings. Whilst appreciating the optional enhancement, integrated grip texture would have solved the problem more elegantly. The included grips work effectively once applied, transforming the mouse's handling characteristics substantially. However, their separate application feels like an admission that the base design requires enhancement.

For those with naturally dry hands or preferring smooth surfaces, the untreated finish may prove acceptable. Those with moist hands or requiring secure grip during intense gaming will find the adhesive grips essential rather than optional.

Button Technology and Actuation

★★★★☆ 4.1

The Pro X Superlight 2 DEX employs Logitech's new LightForce switches. These innovative components combine optical and mechanical technologies, delivering optical responsiveness whilst retaining satisfying mechanical tactility with audible click feedback. They require slightly greater actuation force than competing implementations—a characteristic that may appeal to those preferring deliberate actuation over hair-trigger sensitivity.

Side buttons feature marginally longer travel distances compared to primary buttons. This represents another adjustment for users transitioning from different mice. After acclimatisation, the distinction becomes unremarkable, though it creates noticeably different characteristics between the two button pairs.

After two weeks' intensive use, button coating already shows wear, with the textured finish beginning to smooth on primary buttons. Extended use will inevitably result in polished surfaces—an aesthetic rather than functional concern, though disappointing at this price point.

The scroll wheel responds smoothly with less pronounced detents than models like the G502 X. This creates a different tactile experience—neither superior nor inferior, simply alternative—that users will either appreciate or find insufficiently defined according to personal preference.

Underside Components

The mouse's undercarriage houses the Hero 2 sensor, power button, and generous PTFE (Teflon) feet providing respectable glide. Whilst these feet perform adequately, competitive players seeking ultimate precision may opt for aftermarket alternatives offering marginally improved performance.

The power button's placement prevents accidental activation whilst remaining accessible when needed. The sensor positioning follows industry standards, though some users may prefer slightly forward placement for specific grip styles.

Performance Analysis: Hero 2 Sensor Excellence

The Pro X Superlight 2 DEX incorporates Logitech's second-generation Hero optical sensor—not entirely new, but enhanced through firmware updates applying equally to this model and the standard Pro X Superlight 2, ensuring identical performance characteristics.

The sensor withstands 40G acceleration, tracks at speeds up to 500 inches per second, and offers sensitivity reaching 44,000 DPI. This maximum figure proves extraordinarily elevated—territory I've never approached. Gaming style dictates ideal sensitivity: players with minimal mouse movement appreciate higher DPI, though even professional gamers typically operate between 1600 and 2800 DPI.

Logitech's G Hub software permits three profile configurations for switching between sensitivity settings. Unfortunately, the DEX's minimalist design omits dedicated DPI cycling buttons, necessitating sacrifice of a side button if on-the-fly adjustment proves essential. This represents a curious omission, as the original G Pro Wireless included a discreet button beside its sensor specifically for this purpose.

Polling Rate and Competitive Performance

Recent firmware updates enable 8kHz polling rates. This interrogation frequency reduces input latency substantially but consumes significant resources—particularly CPU cycles—whilst drastically reducing battery life. Reserve this setting for competitive gaming if your PC possesses sufficient processing power; casual players will find 1kHz or 2kHz entirely adequate.

In-game performance proves exceptional. Testing across diverse titles including Warhammer 40,000: Boltgun, Destiny 2, and Counter-Strike 2 revealed the mouse's capabilities. Reducing in-game sensitivity whilst increasing DPI provides an excellent baseline. The DEX responds instantaneously, eliminating hardware as a limiting factor in performance—responsibility for success or failure rests entirely with the user.

The Hero 2 sensor tracks flawlessly across various surfaces, maintaining precision even during rapid flicks and minute adjustments. Zero acceleration or jitter manifested during testing, confirming the sensor's reputation for tournament-grade reliability.

Software: G Hub Simplicity

As customary, Logitech supports its G-branded products through the G Hub software. This application administers mouse configuration efficiently without overwhelming users with excessive options.

The interface maintains admirable simplicity—stripped back like the Superlight 2 DEX itself. Within G Hub, users configure sensitivity profiles (independent X and Y axis adjustment), lift-off distance, polling frequency, and button remapping including macro programming or alternative commands. No RGB controls clutter the interface; the Superlight 2 DEX prioritises performance over decorative lighting.

One particularly valuable feature: Hero sensor calibration. Owners of existing Logitech mice can transfer their accustomed sensitivity precisely through an empirical calibration system requiring simultaneous movement of both mice side-by-side. Whilst seemingly rudimentary, this approach functions brilliantly, ensuring consistent feel across device upgrades.

G Hub supports profile switching, macro recording, and surface tuning. The lift-off distance adjustment proves particularly useful for players preferring minimal clearance before sensor deactivation during repositioning movements.

Battery Life Considerations

Achieving featherweight status precludes removable batteries like those in the G305 (which delivers 250 hours from a single AA cell). The DEX employs a compact lithium-ion rechargeable battery delivering autonomy heavily dependent on polling frequency configuration.

Logitech quotes optimal performance of 95 hours at 1kHz polling. This plummets to approximately 20 hours at 8kHz, with 35 hours representing the midpoint at 4kHz. Users must balance precision against longevity according to their competitive requirements.

USB-C Charging Finally Arrives

Charging modernises with USB-C implementation—finally abandoning microUSB. Logitech's tardiness adopting this universal standard proves baffling, though the change arrives at last. Complete recharging requires approximately two hours.

Minor disappointment: the supplied cable lacks braiding. At £170, such details matter—a premium product deserves premium accessories throughout. The cable functions adequately but feels incongruous with the mouse's otherwise excellent presentation.

The package includes a USB-C to USB-A adapter enabling connection of the Lightspeed dongle via extension cable, positioning it closer to the mouse for optimal wireless performance. This accessory proves valuable for users whose PC positioning creates wireless interference or excessive distance from standard USB ports.

Wireless charging compatibility with Logitech's Powerplay mouse mat provides continuous power during use, eliminating battery anxiety entirely for those investing in the ecosystem.

Value Proposition and Competition

Logitech G prices the Superlight 2 DEX at £170—substantial yet comparable within this category. The company targets professional gamers and demanding enthusiasts. Competition includes the Razer DeathAdder V3 Pro at £190 and WLMouse Beast X Max also at £170.

Remember this represents a specialist tool rather than versatile peripheral. Limited button count and right-handed exclusivity position it squarely towards competitive gaming rather than general use. Productivity users requiring numerous programmable functions should look elsewhere; this mouse serves a specific purpose extraordinarily well whilst deliberately sacrificing versatility.

Comparison to Alternatives

The simultaneously released Pro 2 Lightspeed costs £140—£30 less—whilst offering ambidextrous design and seven programmable buttons at 80 grammes. Those not requiring absolute minimum weight might find greater value in this more accommodating alternative.

Logitech's own G502 X provides vastly superior versatility with numerous programmable buttons and scroll wheel modes, though its 106-gramme mass represents a significant increase. Each model serves distinct purposes: the DEX pursues competitive purity, the G502 X embraces comprehensive functionality.

For Left-Handed Users: Pro 2 Lightspeed

Left-handed gamers needn't despair. The simultaneously launched Pro 2 Lightspeed delivers perfect ambidexterity. This model features double the DEX's side buttons—removable, following G900 heritage—permitting complete removal or selective use of two or four according to preference. Its profile maintains flatter contours without the DEX's pronounced ergonomic sculpting.

Beyond hand orientation accommodation, the Pro 2 Lightspeed offers technical enhancements over 2018's G Pro Wireless:

• Hero 2 sensor with 44,000 DPI (available via firmware update on G Pro Wireless)
• Maximum speed of 888 IPS versus 400 IPS previously
• Maximum acceleration of 88G versus 40G on 2018's G Pro
• Improved autonomy: 95 hours without lighting, 60 hours with, compared to 60 and 48 hours respectively for G Pro Wireless (figures at 1kHz polling)

This represents substantial evolution priced at £140—£10 more than the G Pro Wireless at launch. The Pro 2 Lightspeed merits consideration from ambidextrous users or those requiring additional programmable buttons.

Conclusion

After three lightweight mouse generations, Logitech G delivers a radical iteration of its professional gaming peripheral. As the first asymmetric model in its lineage, the Pro X Superlight 2 DEX exclusively serves right-handed users. The revised and adapted form provides exemplary ergonomics representing its sole differentiation from 2023's Pro X Superlight 2.

Everything else remains identical. Even its Hero 2 sensor's 44,000 DPI specification hardly constitutes argumentation, as the 2023 model accesses identical performance through firmware updates.

Consequently, Pro X Superlight 2 DEX acquisition justifies itself only for users lacking recent Logitech G Pro models. Furthermore, this mouse represents a deliberate compromise: pursuing minimal weight sacrifices functionality. Just five buttons and no on-the-fly sensitivity adjustment creates extreme minimalism probably reserved for highly specific applications.

The G502 X weighs more but offers greater versatility. If weight remains paramount, the new Pro 2 Lightspeed adds merely 20 grammes whilst providing ambidextrous design and seven buttons for £30 less.

For right-handed competitive gamers seeking absolute minimum weight combined with ergonomic excellence, the Pro X Superlight 2 DEX delivers uncompromising performance. Its 60-gramme mass, asymmetric sculpting, and tournament-grade sensor create an exceptional tool for serious competition. Casual gamers requiring versatility should investigate alternatives; this mouse serves its narrow purpose with extraordinary competence.

The DEX exemplifies Logitech's willingness to pursue niche excellence rather than universal adequacy—an approach that delivers exceptional results for its target audience whilst deliberately excluding others. This focused philosophy produces a superior product for those it serves, even as it narrows the addressable market. For the right user, the Pro X Superlight 2 DEX represents perhaps the finest competitive gaming mouse available.
