Regarding my first wireless mouse, it is hard to make a comparison with other products of the same kind, but it works beautifully well. Equipped with 4 buttons and a "wheel" mouse obeys the finger and the eye and offers the possibility, via 2 buttons to the left, to go back or go forward in browsing the Internet . For the rest, outside the wireless system, nothing special. The operation could not be simpler: just plug a little "stand" on the USB jack on the computer and the girl is ready to operate. No need for a reboot or a complicated installation. The mouse requires two batteries. It must, however, remember to turn it off, via a small button after use, otherwise to use the batteries for nothing. I had a little trouble initially used to it, being accustomed to the traditional mouse. In short, once likened this small detail, you will separate more and you!
