During production there are occasional paint coating flaws on some finishes which may show signs of irregularity. The manufacturer deems these items as Factory Irregular (FIR), places a stamp on the product and reduces price.
ALL FIR's, units come with same parts as if buying new and carry FULL 5 year warranty.
