Logitech G Pro X Superlight Tester
Click any button to test it — with double-click bug detection, scroll and sensor checks.
Left: 0
Middle: 0
Right: 0
Back (4): 0
Forward (5): 0
Scroll ↑: 0
Scroll ↓: 0
Click, scroll and hold buttons inside this panel. Right-click menu is suppressed here.
Sensor tracking
Draw slow circles — gaps or straight jumps in the line reveal sensor skipping.
Double-click detector
Any second click within 80ms of the last one is flagged — real human double-clicks are slower. Flags: 0
How it works
The Superlight dominated esports for years, and most units sold are the original mechanical-switch version — which inherited Logitech's double-click weakness. It's also wireless, which adds the two failure modes this test isolates well: receiver interference and battery-related input drops.

Known issues on the Logitech G Pro X Superlight
Original Superlight units develop left/right button double-clicking and, less often, click drops (a press that doesn't register at all). Because it's wireless, USB 3.0 ports and hubs sitting next to the receiver cause stutter and missed inputs that get misdiagnosed as sensor failure. The stock PTFE feet wear thin within a year of heavy use, which users often mistake for tracking problems.
Work through the tester above: click every button and watch its counter, scroll both directions one detent at a time, hold your normal clicking rhythm on the main buttons to bait out double-click bounce, and draw slow circles on the canvas to expose sensor or link dropouts. Want to verify the reported rate too? Run the polling rate test, and test sustained clicking with the click speed test.
Diagnosing your mouse
Click each button, roll the wheel and move the pointer inside the arena; every button, scroll step and the double-click detector report live. Because the test reads raw browser events, it separates a genuine hardware fault from a software quirk — the difference between "my mouse is broken" and "my mouse software remapped a button".
The double-click bug
A worn micro-switch "bounces", sending two clicks for one physical press. The detector flags any second click landing within 80 ms of the first — far faster than any human double-click. Repeated flags on single presses mean switch bounce: a real hardware fault. Contact cleaner sometimes buys time; otherwise the switch needs replacing. This same bounce silently inflates scores on the click test, so verify here first.
Button and scroll issues
| Symptom | Cause | Fix |
|---|---|---|
| Side buttons 4/5 don't register | Browser support varies; driver mapped them to Back/Forward | Disable gestures in the mouse software, re-test |
| Right-click opens a menu | Context menu stole focus | Click once inside the arena first |
| Scroll skips or reverses steps | Failing wheel encoder | Clean the wheel; a worn encoder needs replacing |
| One physical click = two counts | Switch bounce (double-click bug) | Contact cleaner or switch replacement |
Sensor and tracking
Move the pointer smoothly across the arena. Jumps, stutters or a cursor that won't reach the edges point to a dirty sensor lens, a bad surface (glossy or glass), or a failing sensor. Wipe the lens, try a proper mousepad, and re-test before blaming the hardware.
Troubleshooting
› Right-click opens a menu instead of registering
The test arena suppresses the context menu while your pointer is inside it. If a menu still opens, click once inside the arena first so it has focus.
› Buttons 4 and 5 don’t register
Browser support for side buttons varies, and some mice map them to Back/Forward at driver level. Try disabling gestures in your mouse software, then test again.
› The double-click detector flagged my mouse — now what?
Repeated flags on a single physical click mean switch bounce, a hardware fault. Cleaning with contact cleaner sometimes helps; otherwise the switch needs replacing.
Frequently asked questions
› Which mouse buttons can I test?
Left, right, middle (wheel click), and side buttons 4 and 5, plus scroll up/down and pointer tracking.
› What is the double-click bug?
A worn switch “bounces”, sending two clicks for one press. Our detector flags any second click that lands within 80ms of the previous one — far faster than a human double-click.
› Can I test my scroll wheel?
Yes — scroll inside the arena and watch the up/down counters. Skipped or reversed steps indicate a failing wheel encoder.
› Is my mouse data private?
Completely. All events are processed in your browser; nothing is recorded or uploaded.
Common Logitech G Pro X Superlight problems and how to read them
These are the faults owners report most for the Logitech G Pro X Superlight, what causes each, and how to confirm it with the tester above before spending money on a repair or replacement.
| Symptom | Cause | What to do |
|---|---|---|
| Double-click flags on left or right button | Omron mechanical switch wear — same failure family as the G502 | Logitech warranty replacement within 2 years; otherwise switch replacement (many repair shops stock Omron D2F-01F) or upgrade to the Superlight 2, which moved to hybrid switches |
| Cursor stutters or inputs drop intermittently | 2.4GHz interference — receiver next to a USB 3.0 port, metal case or SSD enclosure | Draw slow circles on the tracking canvas; gaps confirm it. Move the receiver to a front port or the included extension adapter, within 20cm of the mouse |
| Tracking feels scratchy on the pad | Worn PTFE feet, not the sensor | If the tracking line here is clean but glide feels rough, replace the feet ($10 aftermarket) instead of blaming the HERO sensor — it rarely fails |
Testing tip: Run the test twice: once with the receiver where you normally keep it, once with the mouse 10cm from the receiver. If results differ, your problem is radio, not switches.
If it's beyond saving: consider the Razer Viper V2 Pro — same weight class and esports focus with Gen-3 optical switches immune to click bounce.
