Lightweight and compact, okay, but there was a huge loss of quality in the image. To give you an idea, for a projection of the PC desktop, the icons are unreadable unless the projector is 30cm from the wall, and the image ... is the size of the PC screen, so no interest ! For sound, no way to change it, and it is too low. I wanted to use in the classroom with my students, I go my way, so watch my videos on the PC. Too bad!
