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.
Summary: We were looking for a replacement for the old overhead transparency projector. We wanted a device that was portable and easy to use. This product could not get any better. We teach management skills to adults, and have participants do written exercises in class.
