having used Foma film, mainly 400, for many years as my only film, I have yet to have any QC problems, yes I have had problems, but mostly user error, I have had as many QC control problems with Ilford and Kodak, no matter how good the QC is mistakes happen, and Foma will replace film if there is a problem without question, I have had 3 replaced due to QC problems in at least 25 years, and they reply quickly to any questions, they have been making films since 1921, sucessfuly so they must be doing something right, I would not change my films even if the prices reached Ilford levels, and as far as being a cheaper option, Ilford HP5* 120 costs MORE than Fomapan 400 120 over here
