The Logitech G502 Proteus Core isn’t just a mouse—it’s a legacy. Launched in 2014, this iconic gaming peripheral still sparks heated debates: Is it a timeless workhorse or a relic overshadowed by modern rivals? After 200+ hours of testing across Counter-Strike 2, World of Warcraft, and daily productivity, this Logitech G502 Proteus Core review delivers a no-nonsense verdict. Spoiler: It’s not perfect, but it’s far from obsolete.
Design & Build: Sturdy, Customizable, and Built to Last
The G502 Proteus Core has that unmistakable 2010s gamer look—sharp angles, aggressive styling—but it’s more than just aesthetics.
- Adjustable Weight System – Fine-tune balance with up to five 3.6g weights (max 138g). I used three for better control in Apex Legends.
- 11 Programmable Buttons – The sniper button is perfect for precise aiming, while macros help in MMOs and productivity tasks.
- Rubberized Grips – Textured sides keep your grip secure, even during sweaty Call of Duty matches.
- Durability Check – Dropped it twice (thanks to my cat). No damage—just minor scuffs on the PTFE feet.
Performance: Precision That Embarrasses Newer Mice
At its heart lies the PixArt PMW3366 sensor (12,000 DPI). Let’s squash the myth: Older doesn’t mean worse.
- Zero Smoothing/Acceleration: Tested at 800 DPI in Valorant, tracking rivaled the Razer DeathAdder V3.
- Dual-Mode Scroll Wheel: Hyper-fast free-spin for scrolling Reddit vs. tactile clicks for weapon swaps.
- On-the-Fly DPI Shifting: Drop from 3200 to 400 DPI mid-game with a thumb button.
Weakness: Struggles on glossy desks. Pair it with a cloth pad like the SteelSeries QcK.
Software & Customization: Old-School Power, Modern Compatibility
The Logitech G502 has been around for years, but thanks to G HUB software, it still competes with modern gaming mice. However, while the software offers powerful features, it’s not without flaws.
1. Button Customization & Macros:
- 11 Programmable Buttons – Every button (except left-click) can be reassigned. Whether you need a grenade hotkey in CS2, a quick-build macro in Fortnite, or productivity shortcuts in Photoshop, the G502 adapts.
- Onboard Memory – Save up to five profiles directly on the mouse, so your settings stay even if you switch PCs.
2. Smart Per-Game Profiles & DPI Switching:
- Automatically switch profiles when launching different applications.
- Adjust DPI on the fly (100 to 25,600) with a dedicated DPI shift button—great for sniping in FPS games or switching between gaming and work.
- Sniper Button – Temporarily drops DPI for precision aiming (can be reassigned for other uses).
3. RGB Customization:
- Three adjustable lighting zones (logo, DPI indicator, scroll wheel) with full RGB spectrum customization.
- Can sync with other Logitech peripherals for a uniform setup.
4. The G HUB Controversy:
- G HUB replaces the older Logitech Gaming Software (LGS), but many users complain that LGS was faster and more intuitive.
- Common complaints:
- Occasional profile switching bugs
- Settings not saving properly
- UI feels bloated and unintuitive

Comfort & Ergonomics: Love It or Hate It
The G502 is one of the most polarizing mice when it comes to comfort. Its aggressive shape is a dream for some, a nightmare for others.
1. Palm Grip – Built for Endurance
- The sculpted hump supports your palm, reducing strain over long sessions.
- Ideal for gamers who rest their entire hand on the mouse rather than hovering.
- Perfect for MMORPGs, RTS games, and general productivity tasks.
2. Claw & Fingertip Grip – A Mixed Bag
- The rear hump is bulky, making it awkward for claw and fingertip grip users.
- Some players adjust over time, while others find it restrictive for fast movements.
3. Hand Size Considerations
- Best for medium-to-large hands (18cm+ palm length).
- Smaller hands? Reaching all buttons comfortably might be a struggle.
4. Weight & Balance – The Debate
- The G502 is heavy compared to modern ultra-light gaming mice.
- Weighing 121g (without extra weights) and up to 139g (with all weights installed), it’s much heavier than most esports mice.
- Adjustable weight system lets you fine-tune balance, but some gamers prefer a lightweight design for FPS games.
5. Left-Handed Users – No Luck Here
- Strictly a right-handed mouse. Logitech has never released a left-handed version, forcing lefties to look elsewhere.

| Feature | Logitech G502 Proteus Core | Razer Basilisk V3 | Logitech G502 X |
| Sensor | PMW3366 (12K DPI) | Focus+ (26K DPI) | HERO 25K (25K DPI) |
| Weight | 121g – 138g (adjustable) | 101g (fixed) | 89g (wired) / 106g (wireless) |
| Buttons | 11 programmable | 11 programmable | 11 programmable |
| RGB Zones | 3 (logo, DPI, scroll) | 11 (full-body RGB) | 3 (logo, DPI, scroll) |

| Price (2024) | $45+ (used/refurbished) | $45 – $65 (refurbished) | $69.99 (wired) / $79.99 (wireless) |
Key Points :
- The G502 Proteus Core still holds up with durability, customization, and its legendary metal scroll wheel, but it’s heavier and lacks modern sensors & wireless options.
- The Basilisk V3 brings more RGB, a better sensor, and lighter weight but no adjustable weight system.
- The G502 X is the clear successor—lighter, better sensor, and available in wireless, but it ditches the metal scroll wheel some fans love.
Who Should Buy the Logitech G502 Proteus Core in 2025?
- MMO/RPG Gamers: 11 buttons excel for Final Fantasy XIV hotbars.
- Budget Builders: Snag a refurbished unit under 50—it out most 60 mice.
- Hybrid Users: Seamlessly switch between gaming, coding, and graphic design.

Longevity Check: How’s It Holding Up in 2025?
After 6 months of abuse:
- Omron Switches: No double-click issues (rated for 20M clicks).
- Feet: Replace stock skates with Corepad Skatez ($10) for smoother glides.
- Cable: Braided sheath resists tangling but needs a mouse bungee.
Red Flag: Discontinued in 2016—buy from trusted sellers to avoid counterfeits.
Final Verdict: A Cult Classic That Still Holds Up
The G502 Proteus Core isn’t top-tier in 2025, but it’s still a great budget choice if you value:
Durability – Built to last with a metal scroll wheel and rugged design.
Customization – 11 programmable buttons and adjustable weight system for tailored control.
Value – At under $60, it offers features that pricier mice lack.
However, it’s heavy, lacks wireless connectivity, and its older sensor is outclassed by modern alternatives. If you want the latest tech and a lighter build, look elsewhere. But for a sturdy, customizable gaming mouse, the G502 Proteus Core still delivers.
