very good bag very good construction, our previous one from the same company lasted us 3 years definitely value for money I highly recommend it

It looks like a quality product, but it has a big "but".
You cannot have it as both a backpack and a wheeled bag at the same time. The backpack straps are "hidden" on the backside with a zipper, which, if you open it to put the child on their back and place it in the correct position with Velcro, eliminates the wheels. Perhaps my description sounds confusing, but for children in lower grades of elementary school, I would avoid it because the conversion from backpack to trolley bag is a hassle, as it cannot be both at the same time.
