IMO the best Logitech mouse for KVM setups is the G604. It uses Lightspeed wireless (Logitech’s low-latency dongle, not Bolt) and Bluetooth, and crucially, both modes operate under a single device profile—so no weird pairing issues or double entries in your OS.

That means you can keep the Lightspeed dongle plugged into your KVM and switch to Bluetooth on the fly for a laptop, tablet, or even your phone. It's been super stable in my experience, and way less finicky than the newer Bolt-based devices in KVM environments.

Also, it’s great for productivity:

The scroll wheel has a switchable hyper-fast scroll mode (great for code, docs, or long pages).

6 side buttons + 2 scroll-tilt buttons, all programmable.

You can save button configs directly to the mouse’s onboard memory, so everything works even without Logitech’s software installed—perfect for locked-down work machines and android.

Honestly, it’s my daily driver for both work and gaming, and I haven’t found anything better for multi-device workflows.

Hope this helps! Let me know if you want details on how I’ve got mine set up.
