Verified Purchase(What is this?)
This review is from: Logitech R400 Wireless Presenter/Presentation Clicker (Electronics)
This works well - you start the PC, plug in the USB dongle, wait about 5 seconds and it then controls Powerpoint.
I have used this on a number of PCs with no problems. The only issue I have had is that it is difficult to judge where the laser is pointing until you turn it on. However, this is my first laser pointer / presenter so this may be typical.
