Summary: Elmo MO-1 is an excellent piece of equipment. In our case, it just was not capable of projecting a large enough document -- i.e., a large sheet of watercolor paper being used in a demonstration class. There were no problems with the machine itself and the image was very sharp and clear.
Summary: In compare to Ziggi, it is too expensive and there is no capability of turning the angle of the camera. However, It is well made and goog quality with light. It was not a good fit for my use with limited budget.By the way, the driver software is not updated for Window8.
