As wiper blades come from different manufacturers, it’s near impossible to sell , or buy , the correct refill on the first try. Hence, Ford stopped even trying and at Auto Zone it’s a crap shoot as to which kind of blade is on the customer’s car.
The el-cheapo all plastic ones are junk.
I’ve tied beam blades yet found nothing better than the Ford OE ( made by Trico ) and their parts house equivilants.
