The fried chicken chain swapped its skinny fries for rustic-looking skin-on chips this month after admitting its old ones were "letting them down".
But fans aren't convinced by the new-look 99p fries with some customers on Twitter saying they're even worse than the old skinny chips, which they didn't like either.
One diner gave them "3/10" and called them "shocking," while another said: "Who knew KFC fries could get any worse… These new chunky ones taste like micro chips."
Not everyone hates the new fries though.
A KFC spokesman said the chain had been "blown away" by the feedback on its new chips.
