Through my work and training I have often to do with presenters of different brands. After this Kensington Presenter I could give it a try, I bought him dirkt yourself as others no longer come for me now in question. This has the following reasons: - Very low weight. The hand, the arm is not tired. - Ergonomic hand conforming shape. Even with small hands to use without any problems. - 20 m reach safely reached (the previous review, I can not understand-I go from a technical fault on the laptop or presenter from!) With good accuracy angle of stuck in USB port on the receiver's laptop also more reach. - Presenter can after the lecture in the blazer pocket or disappear so that the hands are free, for example, if I still would like to explain a subsequent discussion on a flip chart or something iR want someone compliment, or 'once again talking with "hands and feet". The Presenter I lay now not just from somewhere and then not have to look for him ... - The laser is highly luminous and not only as a faint dot, the listeners and - showers barely recognize, demarcate. - Cheap Price. I hope the review is helpful for you!
