I bought a four wheeler from a brick and mortar store six months ago, and it already felt apart. That's why I decided to give this a try. This is the best four wheeler luggage I've used for my recent trips; speeds through airports with ease, even carpeted terminals. No dragging or pushing; it's like walking a bag that walks itself. Makes one wonder why any wheeled bags have only two wheels. Only wish it had a little side pouch or cargo net to shove incidental airport items. Very affordable and great for me as I travel frequently. I will never travel without it.
