Solid keyboard with (in my version) Long Range

Am highly satisfied with the keyboard. The pressure points of the buttons are very balanced.
All shortcuts can be programmed through the software itself.
This applies both to the keyboard and for the mouse.

On the subject of coverage: I put myself in my 5X5 meters large living room diagonally to the point farthest in the room.
(The receiver was in the opposite corner, plus behind my boxes hidden). In between was my couch as an additional disturbing factor.
Nevertheless, a Word document could edit them. Both the mouse and the keyboard.

So I can not confirm that less than 1.5 m reach. No idea why this is, but it seems well admit distinct differences.

Otherwise advantages of sets have already been mentioned in previous reviews. This I do not want to Duplicate.

My gripe is with the mouse. The mouse wheel can be very difficult to press (This does not mean rolling, but really the press !!).

These functions may not need a lot of users, but I use the wheel as a button very often.
Therefore, it would be nicer if it were something smoother.

Nevertheless, I would strike once again.

hope I could help.
