The installation was as advertised and very easy! USB receiver in, use your mouse.
As described, I have very often transports the mouse. The USB receiver I have to repeatedly from the USB port unplugged for fear that somewhere I anecke and exactly the Stick meet with the laptop, which could be broken. Therefore, I have always deposited the stick in the practical compartment inside the mouse. Problems such as the wear I never had.
After a few weeks I realized that the on / off switch, which I constantly operated somewhat loose sat and I could turn off the power partly only with difficulty on or, depending on which side of the switch was just.
Shortly after this little problems appeared, also began the left mouse button, to develop their own ideas and to work times and times not. This meant that I sometimes up to four times had to click until the mouse button has responded. This was extremely annoying.
Then I Logitech written because one has 2 or 3 years warranty on the product. The agent then sent to me immediately a new product from a different model (M187). Either he did not expect me the same model again or it was probably one of known errors in the series of the model, otherwise I can not explain it.
All in all a great mouse that has always worked immediately after plugging the USB receiver. Only the short life are understandably point deduction for the mouse.
