1.) Even 6yr old kids can't open any of those 3 buckles by themselves and their fingers hurt when opening. 2.) The water bottle pocket can only hold below 400ml size or your kid won't be able to put the bottle in. 3.) Even A4 size book can't fit flat inside. 4.) Losening and closing that tie in the main compartment is a challenge even to a 6yrs old kid. 5.) This bag is too tall and too slim to be a school bag, almost like an adult carrying a Northface hiking backpack to mount Everest. 6.) This bag is more of a aesthetic only when going out with kids where the parent can assist the kid anytime. 7.) Total waste of my money.
