I try the mouse in just the first time and am thrilled. The device under Ubuntu 4.14 running with Plug & Play. The mouse is very sturdy by two large batteries it has a pleasant weight. The matte surface feels pleasant. The keys are a little smooth for my taste. The fact that one "click with the middle mouse button" for the (close tabs, copy, ...) the small black button under the mouse wheel click need, I have to get used to first.
But really great is that continued rotating wheel. So you can also scroll super long sides. I missed since I on a desktop PC switched without touchpad am (with whom I could scroll before using a circular motion without interruption and at variable speed). If you want you can through 'pure press switch to the otherwise usual Scollmodus with resistance.
