This box is just the right size for holding a gopro camera, a few mounts and bits and bobs (like cables), some spare batteries, camera backs and the remote control. The foam cutouts are stiff and hold the items firmly in place. Ideal for packing everything you need for a day or two of gopro filming. Keeps everything in one place and provides a reasonable degree of protection - so your camera won't be damaged in your backpack or car boot.
The only criticism I have of the item, compared to say pelican cases I have (although pelican are much more expensive) is that the foam cutouts go all the way to the outside of the box, so there is not much protection for items inside if something impacts the box from the top or the bottom. I would have preferred at least 10mm of foam protection from impacts from top and bottom eg. someone treads on the case which is on stony ground... which does happen! The stone would exert a lot of force on any item inside the case in this situation. So if you need this level of protection, or waterproof then you need to spend more.
