Review on Logitech Signature M650 L Wireless Mouse, Graphite by Mateusz Boguszewski ᠌

The coolest thing about the mouse is the SmartWheel. The bottom line is that with slow scrolling, it works like a regular "discrete" wheel, with nice clicks. But if you spin it harder, it continues to spin by inertia, which is very convenient for long pages / documents. Previously, this was implemented in Logitech mice with switching modes of the wheel, it was immediately made simpler, more intuitive.
