I've no idea why I never posted about the Sunnylife Hard Case.
It's a hard case that works a LOT better than the OEM case in protecting the gimbal of the camera.
It protects more than just the gimbal, though. It also protects the display screen (keeps it from rotating and protects it from scratches/impacts).
I've been using it for close to a year, traveling locally and internationally with it.
I decided to buy it because there were times when I was traveling with the camera, using the OEM case, I'd open the camera bag and find that the gimbal had been pushed out of it's storage position. When it's out of it's storage position, the camera lense can be scratched.
It absolutely locks down the camera's essential moving parts and protects the glass parts.
I highly recommend this protective case.
