Input: Sea salt is more easily administered with a salt mill. This is just a salt shaker that delivers uncontrollable amounts of sea salt and anti-caking agent into your food, and no iodide. The anti-caking agent isn't event that effective, so the salt either comes out in clumps or gets stuck at the exit. Stay away!
Output:
Hard to control the quantity.
