Just got one of this and it's working nicely, it can fit the Mavic Air (without the DJI case), 4 batteries, properller, cables, controller with the controller's stick on, etc. compact and with straps for shoulder. If anyone interested, can take a look at this link https://smile.amazon.com/gp/prod ... =UTF8&psc=1

I bought and returned this. The fit on the drone was very tight. IMO, if you nudge that case enough, the pressure placed on the drone will easily bust up that plastic mavic air.  I've read some folks modifying the case, but you shouldn't have to do that. IMO, the best case is the shell. Then drop that shell in something else.
