Excellent keyboard/mouse combo
I love this keyboard and mouse set. I connect it to my PC via Bluetooth, but I've also tested it with the USB dongle supplied. In both cases, responsiveness is excellent.
Keyboard: typing is very pleasant, the size is contained, the backlighting is sufficient, and the battery life is very good, with a standby mode that helps a lot.
Mouse: ergonomic, with pleasant and very useful buttons and dials. Good battery life.
Simple, practical configuration software (Logi Options+).
Everything is rechargeable via USB-C.
The only minor criticism: a slot for storing the dongle, either in the keyboard or in the mouse, would be nice to avoid losing it when using the whole thing in Bluetooth.
