R400 presenter Bad design,
Verified Purchase(What is this?)
This review is from: Logitech R400 Wireless Presenter (Personal Computers)
It sits nicely in the hand and the left and right control buttons are easy to use. However, directly underneath these buttons, and with no plastic separating them, lie two other buttons.
These lower buttons are easily accidently pressed, especially if you pass the presenter to someone else to use for you.
One of these buttons blacks out the screen. The other takes you out of the PowerPoint slide show and shows everyone the workings of PointPoint. This is embarrassing. My old Logitech 2.4 was laid out better, unfortunately it didn't like having orange juice being spilled on it which is why I needed a new presenter. Sadly, I bought the R400 which is poorly designed. It is pretty but you are always worried that you will accidently drop it out of slide show mode.
Note to Logitech. There should be no buttons below the left and right control buttons. Other buttons should be higher up. Ergonomics has replaced usability.
