First, the mouse using the Unifying USB dongle Logitech works. A very good choice, because, a connection is automatically established between dongle and mouse when both are on. In addition, you can connect with a USB dongle to 6 simultaneous compatible devices. I remember once we had the wireless devices always the press buttons so that a connection is established. Meanwhile, it is with the Unifying station history. Thanks to the small building, the dongle can remain in the laptop.
The associated software provides a permanent condition of the battery, and the included Duracell batteries are promising. 3 years as private users will definitely be a fun.
The laser tracking mouse is innovative, according to the manufacturer every surface is suitable. These things I have tried the same, from rough to almost near-less smooth surfaces and completely agree. When moving the mouse, there was no impairment.
Among the key: the impeller can be moved in 5 directions, an additional button is the possibility of a circuit for the wheel between Snap-mode and run, ideal for hyper-fast scrolling in documents etc. For gamers expected the mouse to be also interesting. The mouse will automatically detect when the PC starts a game. In addition, the buttons can be programmed using Game mode both in normal Windows / Mac mode. Then there are the side the back / forward buttons, and a button which serves as a shift between open programs in the standard.
My personal opinion: A purchase of it's value!
