This is a tested 3M 1700 projector in good working condition. However it does need to be deep cleaned, and has melted plastic on the back (see in pictures above).

It will be shipped with the arm unattached (shown in picture above), with the (phillips)screws in a bag to reattach it. 

This projector is being sold AS IS, no returns. Please look closely at the pictures above, what you see is what you get.
