prima 5 button wireless mouse at an affordable price

Have some time been looking for an affordable handy 5-button wireless mouse and here found it.
Buttons and scroll wheel are accurate and the changeover to the DPI button (2 speeds) is clearly noticeable. Once fleet cursor movements with little hand movement, even slowly with further way for the hand. The brisk cursor movements I find enjoyable. The sensitivity can be well on the operating system in the system settings change "mouse". Was with me but not necessary.
The mouse has an on-off switch. But seems not to be necessary in daily use since it exhibits itself during shutdown of the PC. This can also be "simulated", in which one pulls the small USB transmitter from the computer. After a few Sekunen the "laser" switches off. The transmitter can be easily sink to the bottom of the mouse and is obviously drawn magnetically to the opening and has so secure grip (have the mouse shaken).
Driver software was not necessary, nor was.
Although still without long-term experience can I recommend it in good conscience.
