The noise of the buttons is a bit annoying, but it is not very serious. The plastic is fragile but resistant. No worries transmission. Some say that the buttons are reversed, but they are wrong in fact ... in PowerPoint, to move to the next slide, we go right down (slides are right and the first is upstairs in the tool) . Only regret: no button to view the slide show from the current page.
