The manual one can safely omit. Open the cover on the ground, batteries in, cover for, nano receiver wait briefly in the USB port and. The mouse is super fast recognized by the PC, once installed and there you go.
Impeccable without problems.
The mouse weighs a little more than my Vorgänermaus. However, had a cable and no batteries in her belly. But the weight is relatively unimportant for me, lifted it is rather rare.
The soft-grip surface is very pleasant and the scroll wheel optimally.
The LED lamp indicates that the batteries need to be replaced soon.
Only you have to get used to it that you have to turn off the mouse. Especially in the beginning you forget that very often. A small lamp would be handy here.
Even from about two meters distance the mouse reacts still perfect. Thus, you can work on the TV and the mouse can take the place of the remote sensor.
Just great - I am more than satisfied and can only recommend the wireless mouse.
