Got this in a bundle together with the Yamaha EAD10. This case is quite big and is meant to hold much more than just the module (check dimensions).
The inside has multiple separators you can move around and anchor with velcro, it comes already appropriately set up to fit the module, sensor and power supply. I quickly made a few adjustments to fit my cables, headphones, microphone, essentially merging the contents of my previous bag into this one.
The front pocket is also generously sized and doesn't have any dividers, I mainly use it for notes, ipad and such.
The materials are nice and is well padded, it looks like a soft bag, but it has rigid reinforcements inside each face, hence why I call it semi-rigid.
The shoulder strap has a very large padded section and the main handle is solid as well.
In all this feels maybe a bit "overkill" for its stated goal, but this just makes this more versatile. I'm sure I'll keep using this for a long time for a variety of purposes. For the price it's very worth it.
