I'm studying engineering school and this unit is essential for presentations that stand out. What I like is the ease of use (for me with PowerPoint) and the absence of noise when you press the buttons (this is very important when you are in a small room). I note 4 stars because the price may be a bit high but we feel the quality and I'm really not disappointed with this purchase. I recommend it to all who want to spend their slides with elegance and ease, for you to do the rest!
