Input:
The film did not work.  It would not produce a picture.  It was totally useless.  I have mailed it back to the seller expecting to get a refund, I hope.  Forty-two dollars is a lot of money to spend on film that produces not one picture.  So far, the seller has been nice and cooperative.  We'll see if that remains true.
