BOTH zippers broke off. My husband fixed it, and they snapped off again. My son had it for maybe 2 months before it became unusable ( we need to buy whole new zippers). My son is 6 years old- But he is not particularly rough with his backpacks and has never broken the zippers on ones before. You can replace the zipper's and the bag itself still works- but it was frustrating having both pockets rip off because of cheap zippers. It should last longer than 2 months of normal use.
