I once borrowed the presenter of a friend and have really tried everything: from other rooms etc through doors and walls in the hallway and the presenter has nevertheless works. I was very impressed! In addition, he is really good in the hand, the buttons are very easy and comfortable to reach a "squashing" is almost impossible, and the "black screen function" is especially at the end of presentations very useful!
The only drawback is the lack of a mouse function, but how many times you have to start because built-in videos or links? And if you really need another device you have to buy to hold. This one, however, deserves 5 stars!
