Logitech M100
D0 No Radio — No radio at all. It cannot phone home.
The unplug test
Nothing changes; the mouse only ever spoke USB HID to the computer it's plugged into. There is no receiver, no pairing, no battery, and no Logi Options+ software required for the buttons or scroll wheel to work — plug it in and the cursor moves.
Why this tier: Manufacturer's own product page describes the M100 as a corded USB mouse: 'Just plug the cable into the USB port and M100 is ready for use. No downloads, no setup, no fuss.' No wireless capability is offered on this SKU. Logitech's FCC grantee code (DZL) files numerous intentional-radiator grants for its cordless mice, and no such grant exists for the M100, consistent with a wired-only device with no radio.
