I've been building openlogi.net , an app for controlling Logitech mice and keyboards on Windows — and it's at a point where I'd love for people to try it.

It talks to your devices directly over HID++ (Bolt/Unifying receiver, Bluetooth, or wired), so everything stays on your machine: no account, no cloud sync, no telemetry.

The porting story: this began as a port of the excellent Rust project AprilNEA/OpenLogi. The original leads on macOS and Linux - Windows is an early, untested preview there. I'm on Windows, so rather than bolt Windows support onto a Rust/GPUI codebase, I rewrote it in C# / .NET + Avalonia.

Because the whole thing is built around Windows first, it's grown more capable on Windows than the original's Windows preview — fuller device support, RGB lighting (per-key colors and effects), onboard and per-app profiles, multi-host switching, and a proper installer. It's an independent project, but huge credit to the upstream OpenLogi for the foundation and the reverse-engineering work.

What it does:

- Discovers your devices + shows battery level

- Button remapping

- DPI control + presets

- SmartShift (wheel ratchet) tuning

- RGB lighting — colors, effects, brightness

Why you might like it:

- Small + self-contained — ~16 MB installer (or a portable zip), and you don't need .NET installed

- No account, no telemetry, fully open source (MIT)

- Installer and a no-install portable build on the releases page

I've tested it on the hardware I own, and since Logitech's lineup is huge, I'd genuinely love to hear how it runs on your device — open an issue with your model and what worked. One quick tip: close Options+ first, since both apps want to talk to the device at the same time.

I'm sharing my experience with Logitech support in case it helps anyone else dealing with the same runaround. Nearly a month, four different agents, the same copy-pasted "by design" response three times, and a formal denial of warranty.

I bought an MX Master 4 on 31 January. It worked perfectly for several months. Around mid-May, the left button started clicking noticeably louder and softer than the right, causing accidental clicks that disrupt my workflow daily. This is a mouse marketed with QuietClick technology 90% less click noise.

**9 June** — Opened a support case. Submitted a video demonstrating the issue, serial number, and purchase receipt. Agent #1 escalated to a "higher support team" and promised a response within 48–72 hours.

**12 June** — No update. I followed up.

**14 June** — Agent 1 responded saying the difference is "expected and normal" because "the left button has a larger surface area, which naturally produces a louder clicking sound." Case dismissed as by design.

**Same day** — I replied disputing this. The mouse did not behave this way when I bought it. I also linked a Reddit thread where another MX Master 4 user reported the exact same issue — and that user had received TWO replacement units with the same fault.

**19 June** — Escalated again. Another 48–72 hour promise.

**25 June (6 days later)** — Still nothing. I chased again.

**27 June** — Agent #2 asked me to record a brand new video showing the serial number, a handwritten ticket number on paper, and the issue. I complied.

**1 July** — Agent #3 (replied saying he's "closely monitoring" the case. No decision, no timeline.

**1 July** — I sent a formal escalation email requesting a concrete deadline.

**5 July** — Agent #4 replied with the exact same "by design" explanation from 14 June. Word for word. As if the last three weeks never happened.

**5 July (same day)** — I pushed back again. Agent 4 then formally denied the warranty claim in writing, stating they are "unable to proceed with a replacement or refund."

So to sum up: nearly a month, four agents , two video submissions, multiple broken 48–72 hour promises, and the final answer is a copy-pasted response I already disputed three weeks ago — now with a formal denial attached.

Not once in any response did Logitech address the fact that the behaviour developed months after purchase. Their entire position is that the click difference is "by design" — but a device doesn't start behaving differently after months of normal use because of its design. That's a defect.

I've seen other posts on this sub from users dealing with the same support pattern.

All I'm asking for is what the warranty entitles me to: a replacement or refund for a device that developed a fault. That's it.

If you're going through something similar document everything and don't give up.

Nothing works. I've kept it charging for a couple of hours, I've tried using it plugged in, and nothing. Does anyone know how to fix it myself? (It doesn't have a warranty because I bought it secondhand.)

Found a 3D printed lightweight shell design for the MX Master 3 online (honeycomb/lattice pattern to cut weight) and decided to give it a proper finish. Printed it out, then hydro-dipped it in a carbon fiber pattern film and topped it off with a clear coat for protection and shine.

Really happy with how it turned out — the exposed lattice work looks great with the carbon fiber texture, and it's noticeably lighter than stock without feeling flimsy. Transplanted the scroll wheel, side button, and thumb rest over from the donor mouse without any issues.

Now I'm torn on whether to touch the switches at all. Stock ones actually feel fine to me, not mushy or anything — but since I've already gone this far with the mod, part of me wants to go all in and swap them too. Anyone here swapped switches on an MX Master 3? Worth it, or should I just leave well enough alone? If it is worth doing, what switches would you recommend?

So I recently started using macOS, and using my mouse is so hard; it feels so clunky. Apart from the os being built around the trackpad, the MX feels so bad and so off-axis. Am I doing anything wrong? I tried to use it. Should I sell it?

I just got the MX Keys Mini for Mac because I wanted something smaller than my Craft keyboard. And the backlight is way too bright, even on the lowest setting. The keyboard on the left of the image is the MX Keys Mini and the one on the right is the Craft, both on their lowest backlight setting. Is that normal, or is it a defect?

Some of you might know my other Logitech mouse apps - BetterClick (click customisation) and Sensurf (haptic web scrolling).

I always felt PC/Mac gaming missed the haptics you get in console gaming. GameHaptic uses the Logitech haptic mice to bring the experience to computer gaming.

You build a profile per game: map a recoil or movement or jump haptic etc to keys and clicks in game - whatever makes sense for your mapping. It auto-detects your active game and switches profiles automatically.

No game file modifications, no input lag.

Been running it in my current games and it has really added a lot to the gaming experience, and is another use case for the great haptics embedded in these mice!

Dont want too lose the dongle in a drawer.

My keyboard and mouse are old by today's standards, but I refuse to upgrade!

My G710 got deep cleaned and SteelSeries Prism keycaps installed as they original ones were crumbling.

My G402 got a replace shell and deep clean, looks like the day I purchased it!

Anyone else here using the G710 it G402 still?

Cheers

Following additional requests for my transparent shell concept of the Master MX4, I created a variety of new color options.

Thank you all for your interest in my concept art.
This time, I've put together a collection of more vibrant and bold color variations.
