Mouse:
The mouse is small, which could be problematic for some. I myself have relatively large hands and use it 5-8 hours a day - problems I had not. Otherwise, neither positive nor negative points because it is a standard mouse.
What the deduction?
Vexed and cursed several times I have about the absence of the Caps Lock and Num Lock lights. Especially with online banking, password input, etc., it is very cumbersome, that the status of the parking / Num Lock key is not "normal" to determine. Here you have somewhere "test letter" to check. Of course, such a light goes on the batteries, but in times of LEDs and because the lamp only comes on when the button is "on", no reason for me to renounce it. These status lights should not be missing at a full keyboard.
So overall a decent set that is very good for everyday use, but has minor weaknesses that could annoy the one or other.
