I have been using this bag for a couple of months now and am very happy with the protection that it provides.
The only real issue I have with it is that when the backpack staps are attached, there is no real way to keep them from dragging along the floor when using the wheels rather than carrying it.
It would also be better if the section that opens would lie flat, or at least out of the way, to allow easier access to put the saxophone in the case.
Overall I am happy with the case, and think it is excellent value compared to some of the others on the market.
