Product review (2 stars): Teflon Comes Off!  Do not buy, not food safe.
It worked... just wish the film wasn't on the ice.

Update: Film that was on the ice is from the paint coming off of the ice tray and embedding in the ice.  I'm contacting the manufacturer, but I'd by a different unit.

Update 2:  The coating is Teflon, and this is a known issue with the part.
