I touch it fast times together:
The beamer make a hammer image even if it is light.
I've had more expensive devices and have not projected a good image.
The only drawback: You can hear the device.
At first I was not sure if I should keep the projector, then I invited a friend to listen to another opinion. He was excited by the image and the volume did not bother him, since a PS3 approximately identical is when playing a DVD.
I'll keep the unit now that the image and the 3D is just great.
