I have had that backpack for over a year. I have not had a single issue with it. I got it on sale from banggood for $49 with free shipping.The "same BASIC" case here, shipped from US warehouse: Realacc Backpack Hardshell Case Bag Turtle Shell Waterproof For DJI Phantom 3
Quality not as good but still very usable (depends on your real needs) for a LOT less money. I bought the "soft" case, arrived in about 8 days, instead of the turtle shell and it is actually pretty nice. Everything fit very well inside. Just my $.02
