Review on Waterproof Rolling Laptop Backpack, MATEIN Compact College Travel Bag with Wheels - Fits 15.6 Inch Notebook, Carryon Trolley Luggage Suitcase, Business Bag for Men Women (Black) by Jennifer Davis

May be for adult use only for flying but I bought this for my grandson to replace his wheeled backpack. The grip is much more difficult to control than the rectangular one, and the single bar instead of the rectangular one that pulls metal down to grab isn't as comfortable. The single rod is difficult to control, the backpack is easy to twist, and once the handle is pulled out and stumbled, the pull rod will dent, now it is difficult to retract easily. I'll come back to the double stock with a full square grip. Easy to use and work smoothly. More control
