That bag looks great too! I never noticed that one I actually like the individual storage of the drone and the bag. I may have bought that instead haha. O well. The only benefit to the drone guard is the thick plastic like protective shell on the bag that helps if the bag is dropped or tossed!I have been looking at this one:
