Cheap and good mouse

The mouse has now been 1.5 months with the keyboard Logitech K360 Keyboard black cordless (German keyboard layout, QWERTY) proved its worth in use and has proved.
The receiver is in the front USB port of the PC. He does not fall to continue and the reception is perfect.
The mouse also offers the necessary precision in games and at the same time have the amenities no more cable.

Some more about the Unifying receiver:

The receiver operates on a fixed frequency / channel. Pairing (if, for example. Keyboard and mouse to be used with a receiver) the frequency / channel to be changed at the terminal (mouse, keyboard).
By Keyboard Logitech K360 Keyboard black cordless (German keyboard layout, QWERTY) I still have a second Unifying receiver. My idea was that I Paire mouse and keyboard with two receivers, a leave stuck in the PC and a laptop in. The device, which is currently switched on, so takes the input from the mouse and keyboard. This is not possible because you can only adjust the frequency / channel of a single recipient mouse and keyboard ever.
The only possibility: the recipient reposition repeatedly in the laptop / PC, depending on which device is being used. But is in my opinion is by no problem.

The product has also to extend an on / off switch to the battery life. Since I am very forgetful, this switch is permanently On. How this affects the life, I will tell in a few months or years (the first battery replacement) here.
