I bought this fender after the original on my Huffy scooter cracked in a bad pothole. Huffy doesn't sell any replacement parts for their scooters, but I was delighted to find this alternative. It looks and fits the exact same, right down to the metal piece that locks into the top of the scooter when folder. Would buy again (and likely will, given the potholes in Chicago).
