New input case for you: Did you ever buy something and get more than you expected? Well this is one of those times. First, it performs as advertised, and works well. But then, that's what we pay for and that's what we should get. What I didn't expect is it shuts off when it isn't being used therefore the batteries should last forever - well, not forever but for a long time. When it wakes up a green LED comes on letting you know it's awake and the batteries have enough power to support your work. The instructions tell you when the battery (one AA cell) is nearing the end of its life, a red LED will come on. I haven't used it enough for that to happen but I'm sure it will. If that doesn't work as advertised, I will be on with a follow up. The instructions also give you an option to d/l software to take advantage of Windows Eight and move the screen back and fourth in addition to the more conventional up and down. I haven't tried that little feature but when I do, I'm sure it will perform as advertised. Finally, and this is a small item, - I'm talking about the antenna. It's a tiny little thing. It only protrudes from the USB port a 1/4 inch (6mm). You don't even know it's there. The only down side, the mouse is a little on the small side, perfect for the small or average sized hand but some ham handed person may find it too small for them.
Output:
Wireless Mouse
