Benefits:
Conveniently +
+ Receiver is small and "disappears" as the USB port
+ Laser Pointer
+ Additional buttons like Close window / switch etc.
+ Very thin, can sometimes be put in your pocket if you need to write something / explain in detail
Disadvantages:
- Keys are not difficult or be felt, one must often look where the button for next slide is. Especially at longer presentations comes the not really nice and "skillfully" over
- Unfortunately, the machine is after about 6 months operation broke down. Once the presentation is started it will jump from slide to slide is completed by the Presiding.
- Since the main keys and the key for the LP are close together and it's not possible you are sensing on which button is pressed, it can prevent that, instead of the next slide the laser on and off makes.
Conclusion: Cheap, practical device. Unfortunately, not suitable for continuous use and longer presentations. Buy recommendation must present occasionally only for people. For continuous use, I would still buy myself the Logitech model.
