Summary
A lighter, wired-only rewrite of the old G502 shape: 89 g, LIGHTFORCE hybrid switches and a reversible DPI clutch, with no RGB and no tunable weights. Check the grip before you buy: the cable is fixed, the side grips are rubber, and the ratcheted scroll wheel is the part owners argue about.
Strengths
- At 89 g it is far lighter than the 121 g G502 HERO, and owners call the drop a joy.
- LIGHTFORCE optical switches are aimed at the double-click failures that hit older G502s.
- The reversible, removable DPI clutch suits different thumb reaches and stays attached.
- The dual-mode wheel still free-spins and adds programmable left/right tilt inputs.
- The right-handed shape feels well-built and works for office use, per RTINGS.
- No RGB on the wired model, which many owners prefer.
Weaknesses
- The cable is fixed, and at least one long-term owner calls it awful.
- The rubber side grips draw complaints from owners.
- The ratcheted scroll wheel divides owners: RPS calls it scratchy and loud enough to return the mouse.
- The scroll-mode toggle is a hardware switch and owners say it is too firm.
- No tunable weights and no RGB, so old G502 habits do not carry over.
- Too large for small hands and bulky for a laptop bag, per RTINGS.

Full research notes and sources
Shape, weight and switches
Logitech rebuilt the G502 X around a thin-wall plastic exoskeleton that cuts weight to a claimed 89 g. RTINGS measured 83.7 g and Tom’s Guide lists about 3.1 oz, so the real figure sits just under the marketing number. That is a large drop from the 121 g G502 HERO, and it is the first thing owners mention.
The primary buttons move to LIGHTFORCE hybrid switches, which combine optical actuation with a mechanical tactile part. The goal is to end the double-click failures that plagued earlier G502s, and owners report no double-click issues so far. There is no multi-year reliability data yet, so treat it as a well-aimed fix rather than a proven long-run result.
Scroll wheel and buttons
The wheel keeps the G502’s two modes, free-spin and ratcheted, and adds left/right tilt inputs that G HUB can program. The ratchet is where owners and reviewers split: Rock Paper Shotgun finds it scratchy, crunchy and very loud, enough to return the mouse, while another owner reports the wheel continuing to scroll in reverse after input. The mode toggle itself is a non-programmable hardware switch, and owners call it too firm.
The DPI-shift button is the standout hardware change. It can be flipped for different thumb reaches or swapped for the blank cover in the box, and unlike some rival caps it stays attached. Button counts differ by source — 9 on Tom’s Guide, 11 on Rock Paper Shotgun, 13 when a community guide counts wheel tilt and DPI shift — so read the number as a counting method, not a fact about the shell.
Software and reliability
Logitech G HUB handles DPI and per-game profiles, and owners say it works fine. Five onboard profiles are listed, though that count was not re-verified against a first-party page. The wired model has no battery and no dock, so running costs are nil: no batteries, no charging, no subscription. Logitech’s warranty term was not verified from a first-party page.
Is it worth it?
At $79.99 from Logitech’s US store in October 2026, 20% off the $99.99 MSRP, it is a fair buy for G502-shape loyalists who want a lighter wired mouse. Newegg lists the black model at $79.99, CDW lists both part numbers at $99.99, and the launch price was $80 in 2022.
Which model this is
This page covers the wired base model of the G502 X family, sold in black and white under part numbers 910-006144 and 910-006136. It uses the HERO 25K sensor. Do not confuse it with the G502 X LIGHTSPEED and PLUS wireless models, which add a battery and, on the PLUS, RGB; the wireless LIGHTSPEED now shows a HERO 44K sensor on some regional pages, but the wired model remains HERO 25K.
