Physical - Lightweight - Nice quality finish - Mouse clicks are very quiet! - From of the mouse is a bit wider than rear, not necessarily a negative but felt different
Functional - To answer my own question posted, the f1-12 keys are default and the cool sleep, dim brightness, etc keys need the fn key pressed in conjunction. Good! - Everything else works as intended so far. - Sleep mode sounds nice
Room for Improvement - Mouse wheel clicking and rolling could be quieter (my $10 Logitech was) - Missing my alt mouse wheel clicks from my logitech (pressing to the left or right to navigate back/forward in browsers) - Keyboard by no means loud, but not a drastic change from my previous non-silent one - Minimal, but would be nice to have on/off for mouse and keyboard
Overall I'm pleased and would recommend. I bought this to not wake my sleeping baby and it is working.
