Portable Rolling Sample Case with Wheels - Durable & Lightweight for Trade Shows, Business Travel, and On-the-Go Professionals

I am a college professor who has to regularly carry bulky books, reams of paper, lunch, my purse, and more to my courses. I do not always have the time to go back to my car for anything, either, so I need a sturdy rolling bag with good internal space. I have had to keep replacing bags when they tear or, more likely, when the wheels stop working and there's no way to fix them.I wasn't sure at first that this harder type of case would work out, but it has the perfect dimensions, not too huge, not too small. It keeps everything dry and protected. The motion in the wheels and retracting handle is smooth. The front flap has pockets for things you want to keep on hand. The side pocket is deep enough for your phone, if you want to keep it where you can get at it. I've also used it as an overnight bag to a hotel and it worked like a charm. I've had it since late September and used it a lot and so far it has served me well. I hope it will be my mobile command center for a long time to come.
