A SJCam 4000 fits perfectly, and most of the plethora of accessories shipped with the same origin will require some sort anyway. The cuts of the inner foam does not make a good use of the storage space in my opinion, but all will be well protected anyway. Not really room for a floatie or monopod for example.
A pivoting handle would have been nice, there it is fixed, and the whole is large and far from being a lightweight, harmless little when you take the plane. The outer material easily shows fingerprints.
Good case, I take off a star for the price compared to the competition, although there we are treated to a brand.
