for the mouse in the middle i somehow invented the scrolling so when i move the cursor up it goes down and down it goes up so you know how to reverse it back to normal?
I jus bought one. I's very inexpensive and as good as a Logitech for twice the price. The new ones are a little different from the one in the video. The storage for the USB dongle is inder the battery cover so it can't fall out.
