I have the mouse over a year in use. It is almost always plugged in my laptop and will not turn off. Installation was easy, as announced. Simply the USB stick in and off you go. Well, I think that you can tuck the stick in your mouse, if you nevertheless times takes the laptop on trips. The batteries last for very long, even though the mouse is used daily. (And it is not the expensive batteries in it) I have maybe one or two times changed so far. So in our household, three of these Logitech M185 in action and we are all very happy. Would I buy again and recommend it to anyone to buy.
