I use a similar product called WetFire. Pretty much the same thing but it comes in marble size cubes that you can crush to make a bigger tinder pile, leave whole to burn longer, or break into smaller pieces to conserve. I carry a ferrite rod in my knife sheath to make a spark with and it usually only takes a couple of tries to get it lit. I carry WetFire in my mountaineering pack, hunting pack, first aid kit, survival kit, and my truck. The old Scouts trick of rubbing cotton balls in Vaseline and storing in a Zip Lock bag works good too, or you can even use crayon shavings.
