The Presenter is overall very successful. The functions are very well mounted, ergonomics very well, everything as it should be. The green laser is very bright and easily recognizable even in not darkened rooms. I have the vibrating timer function previously used, as I read off the time on the screen. Lecturers who do not use Moderator view, this feature is certainly very good, as it is inconspicuous than ever to look at the (bracelet) clock. The only thing that bothers me quite annoyed or is partially insufficient processing. The battery lid wobbles, which simply Nervet when you hold the thing in his hand. Not audible keys or buttons very quiet noises are usually a good figurehead Mouse / Presenter / etc. Unfortunately not at R800. The buttons and the laser button are clearly audible, especially when multiple slides forward or backward clicked, this sucks.
It may be that this criticism one or the other to strictly occurs, but the noise bother me, because they make a certain elegance to naught. I think for 70 Euro you can but that's expected.
