The keyboard and mouse both work great and install easily together. I did realize rather quickly that the keyboard isn't backlit at all. When my computer arrives, I hope it has ambient lighting for me to see the keyboard. Otherwise, I will have to purchase a different keyboard that lights up, so I can see.
Functionally, the keyboard is great. It has num lock, caps lock, and battery indicator LEDs, which I really like. The keys are typical of today's keyboards, unlike the keyboards of old that had a nice tactical click and feel. I gave it 4 instead of 5 stars because it lacks heft, and the mouse is a bit small.
