I purchased this for my PRVKE 31. I carry a camera, up to 3 lenses, Mavic Pro and the accessories for each. Everything was in compartments based on size, not function. The Mini Cube allows me to keep the drone and all it's accessories, organized, protected and separate from camera gear. The additional benefit is I can easily remove the drone stuff when not needed on a project, or carry it solo if only flying. The only minor downside is a little extra weight and the cube forces me to loosen the rolltop by 1 loop to accommodate. Recommended.
