Do yourself a favor: DO NOT BUY THIS PRODUCT! After only a month and half of use the handle came off. I try to glue it back with Gorilla Glue, but it didn't hold the glue because the metal of the handle is not solid it does not hold the glue on. Then my son started carrying it in his back, and after some backaches because it was too heavy, I gave him his old backpack from 2011 to roll to school. So save your money for better product. It is a piece of junk...

I saw the bad reviews, and I realize now it was a mistake buying it...
