This bag is pretty much everything I wanted and is of great quality, storing discs in a neat and easy to access fashion.
The biggest annoyance / downside is that it falls over very easily and is hard to stand it up as it's meant to be. To resolve this I 3D printed a stabiliser that is glued to the bottom that moves the pivot point of the bag more towards the middle to resolve this.
This modification stands up far better than it did previously no longer falling over if you breathe at it. I'm sure the bag design itself could be improved slightly by the manufacturer by making the bottom of the bag more rigid and having the bottom angled by about 15 degrees to tilt the bag away from the straps when on the ground.
Additionally I have designed and 3d printed a mod to hold my grabber and tripod in place within one of the side pockets so I don't lose them so easily or feel them clattering about as I walk.
I want to stress that the design of the bag itself is fantastic and I thoroughly enjoy using it!
