Review on Microsoft Wireless Comfort Desktop 5050 (PP4-00001), Black: Superior Ergonomics and Performance by Jamar Gow

I don't even know where to start. But "out of the box" nothing works. For example, I'm used to pressing F2 in Windows Explorer to rename the selected file. In Excel, you can use F2 to edit the cell. Those things don't work. I have no idea how to get F2 to work normally with utility stuff. Mouse scrolling is slooooooooooow. Again, the utility allows you to change the speed between "slow" and "fast" using the scroll bar. But actually nothing happens. You use the scroll wheel in the middle and the page barely moves. In addition, the scroll wheel's response is very poor. You start spinning the wheel for a while before the scrolling feature kicks in. I've been using this KB/Mouse for over a week now and have decided to throw it away. Time. And I use it with another Microsoft product, Surface Pro 3! No excuses.
