After reading many bad reviews about some of the Smatrees cases I was a little skeptical. Pros: May be waterproof but honestly I wouldn't trust it. You can see in the pictures that there is a big difference from the advertising pictures.1. The drone cutout is so large that the Mav 2 Air just floats and doesn't stay in place.2. The cutout for the controller and joysticks is just awful. The controller doesn't quite fit with or without joysticks.3. I don't have SD card slots either.4. The battery cutout is sloppy as shown in Figure 4. The loading cutout is also unusable, see attached picture. Definitely the last Smatree product I will ever buy.
