This 2.4GHz RF Presenter is only as big as a regular laser pointer with a mini size receiver attached to the end part.  It uses radio frequency technology which allows you to control slides in any presentation without any interferences with other remote control devices.
In addition, it’s a presenter in green laser beam, brighter than any red laser.  Better yet, after the presentation is over, simply store the USB receiver back to the laser pointer and you won’t be losing it.  It’s just this handy and the best choice for your next presentation.
