I have severe and chronic back problems and have looked long and hard for a lightweight spinner case that I can easily pack and manoeuver. This is it. It holds a lot for its size, moves easily, doesn't tip over, and is very easy to pack because you put everything in one large section and then put down the lid and zip it up. I have the 21-inch size. If you forget anything or want to be able to easily put your hands on something, you can slide it into one of the outside pockets. I highly recommend this suitcase. I purchased mine on Amazon for a better price than I could find on sale in NYC.
