The ability to divide the compartments, add and subtract instrument and vial attachments and not worry about quality is great. I’ve taken mine on jobs and expeditions around the world and it’s been big enough to hold my essential diagnostics, primary health care, trauma, basic meds and tools needed for remote medic work. Of course, it’s bigger than a small first aid kit, which obviates your primary role within a team or group. It will hold what you need to keep things going. If you need more- make sure you have good Comms; as that’s what will keep your pt alive. A good product from a really good company.
