I've used it for two years now, dragging my amp at least a few times a week (mostly in the back of my car) from different places and therefore wanted to keep the weight down and maximize portability, so a road case was definitely out of the question.
It holds together perfectly well, however it doesn't protect the bottom of the amp, which a buyer should be aware of, so I'm usually (when possible) transporting it upside down to minimize wear and tear of the bottom side of the cab.
It is although a high quality product and I could definitely recommend it.
