They simply can't be compared to anything else. Every time you sit down to work, you feel lucky to have them. The feeling is so addictive that it makes you want to write non-stop.

Simply the best keyboard-mouse set for office work. Silent, with immediate response, satisfactory battery, good software, and above all, Logitech quality!

Sturdy construction and battery life that lasts up to 10 days for the keyboard (with key lighting activated) and 15+ days for the mouse.

It has a motion sensor and the keyboard lights up when you bring your hands close. Very convenient.
If I could change something, it would be the mouse. I would prefer to get the vertical version as it seems more ergonomic to me.

The package so far (3 days) is excellent,
the Logitech software (Logi Options+) DOES NOT support Windows 7 - it doesn't allow you to install it, it requires Win 10 or 11. the previous version (Logitech Options) doesn't recognize either. so if you have Win 7 you can't make any settings for the mouse or keyboard. Logitech should have mentioned this BEFORE the purchase!
