I've not purchased any of the items; it sounds like you plan to and I hope you write a review if you do.

I am not a big fan of magnesium for emergency fire-starting. Generally the wind blows the filings away before you can ignite them, and they only burn for a seconds. You need more tinder to turn that brief flame into a fire. Eg if you have a hexamine fuel tab and that fire rod, you'll be struggling to get the fuel to burn. A cigarette lighter is better.
