This pico projector fits in the hand and is easy to understand realtivement even if the control panel keys are not precise enough. The internal memory is handy. In terms of its luminous power, it's still a pico projector with 40 Lumens, no prjecteur a movie, but I still think he is doing well. It will still be able to darken the room to appreciate the reasonable image quality. It has a screw thread able to be placed one foot "type photo foot) and AC is very convenient. As part of my use, its internal battery helps me a lot, I would do this choice without hesitation.
