Also is the mouse, even though it is slightly less for my taste, very well and ergonomically in the hand. Also the low weight is fully in order, I never was able to work so well with a Bluetooth mouse.
The operation is slightly out of hand. She has a left and right mouse buttons, a scroll wheel with click function, and on the left a small button.
According to the manufacturer Samsung, This indicates that one should use the mouse with the best Android devices from their own home with at least Android 4.4 or higher. So made 10.5 WIFI as my Galaxy Tab S.
However, the mouse also works with other Android devices properly.
However, the buttons each have a slight different function than a conventional mouse, for example to a PC running Windows.
The key assignment:
Left mouse button = As usual, you can start programs and just click stuff.
Right mouse button = How to consider a Back button. (No setting button as in Windows)
= Mouse wheel scrolling and zooming, by pressing on the scroll wheel, this can be seen as the Home button.
Page key left = multitasking button by pressing and to get into the settings.
The runtime can be proud of. The mouse is powered by AA (Mignon) batteries, but batteries can be sharpens. In my experience, so keep a battery in spite of several hours a day 3-5 weeks.
I can definitely recommend this mouse. From me a strong buy recommendation
