I use them - and they are getting better:

But Photo Engineer is right - it shows how hard it is to restart a line. Worst thing that irritates me is that you need to shield picture when is out. With old polaroid films one big part of fun was to look at a picture how is slowly appears in front of your eyes .

If fuji makes instax in B&W - I would not have need to use impossible films.
