The Presenter is called "Professional" and rightly so. The features to price ratio is actually very poor because one with the presenter actually "only" can control presentations and a laser pointer has.
One has to be aware of when buying that you buy a Presenter and any multimedia remote control for the PC. There are other products.
The advantages of the presenter over other similar devices are:
- The very good ergonomics, the presenter is like a flatterer in hand
- The battery indicator, you know if you should have replacement batteries Griffbereit or not
- The green laser, is very high and can be seen still good even in poor lighting conditions
- Plug and Play, also works on Mac computers Easy (Linux systems I could not test)
- Easily accessible and well-to-sensing buttons, keys each forming a trough
- ON / OFF switch implemented as a sliding switch
- No status LEDs
