That’s an absolutely awful video. Loud, obnoxious, disingenuous and not even remotely as funny, informative, comprehensive, or clever as the idiot who made it thinks it is. It’s valueless content made to be ingested and served up by an algorithm.
They’re usually set up so one is a standard pointing device and the other is used for content scrolling. I also had one customer who wanted both as pointing devices, but the left one with DPI set for very fine movements.
SHH, IT’S OK, EVERYTHING’S FINE, YOU DON’T HAVE TO SHOUT, BUT YES, IT’S GOT AN F-ROW, YES. IS THAT SO VERY WRONG?
