One thing i found difficult though was telling apart the three buttons during a presentation

Finally gets a fifth star for having a place to store the pc usb dongle under the battery cover where it wont get lost

Could benefit from a more raised texture to prevent looking down and the laser is an onoff button and sometimes it is inadvertently turned on and left on

Would be nice if it was press switch that turns off when the button is released

The laser is equally good and easily visible so long as the screen is not in direct sunlight which would wash out the projector image anyways

Note that this red laser will obviously not perform well on lcd screens
