The mouse is extremely comfortable to hold and also looks very good. It was important for me, especially the cable, I'm not a fan of wireless mice. Even after several hours in front of the computer mouse is still comfortably in the hand.
That you can turn off the friction of the scroll wheel is a very good feature that I now also use very often, I can hardly think away, class :)
After this mouse is definitely one thing, my next is again a Logitech!
