Sleek, practical, working properly

I can agree with other reviewers only: A great device! I was convinced that very space-saving, laser pointer and remote control in a run, with AAA battery, and running in a matter of seconds, whether in Windows or Mac. And if you use multiple laptops, simply plug only the USB wireless adapter to - and does everything the same. You can also control the volume thus, and make a push of a button the screen goes black and then on again.
Minus: The manual is very small, the logic of the control buttons take some getting used (the down arrow on to say, the up arrow backward).
