First, the size and strength of the case is perfect. Heavy enough to protect the Mavic but light enough to easily carry around in a backpack or with my beautiful 10 year old daughter as a video assistant. Second, the zipper is strong and the padding inside the case is soft, keeping it secure. has multiple Velcro straps to keep things secure when you turn the bag upside down. (remember the open logo) Those straps and velcro aren't really needed and are pretty flimsy where they attach. If I lost it I would buy another one.
