I did a forum search and didn't find any discussion of Sure2Burn fire starters. I found them at Home Depot--$3.95 for a package of 12 (33 cents each). Each one is small plastic bag about 2x2 inches square, filled with a solid listed as "Aliphatic hydrocarbons, Urea based resins, and Parrafin."
The box states:
Convenient, easy to use
Replaces lighter fluid
Non-petroleum based--prevents unwanted odor and taste
Lights even when wet
Safe, non-toxic
Ideal for lighting charcoal grills, fireplaces, campfires, and more.
I tried one a couple of days ago to light a charcoal fire using a metal chimney. I had to do a little improvising as the chimney is designed to use a wad of newspaper directly set on the grill. I couldn't put the Sure2Burn pkg on the grill since I feared it would fall through. So I put one layer of charcoal in the chimney and then I lit Sure2Burn and placed it on top of the layer. Finally, I filled the rest of the chimney with charcoal. The starter worked great. It is much better than newspaper which smokes a lot and generates ashes.
There is a youtube video review
here.
As he states in the video, they can be burned when wet, and they last for 7 minutes at full burn, then 2 minutes more at a reduced burn. With a little prep (again shown in the video) they can be started with a sparking device.
They company that sells them is Char Broil although I couldn't find the Sure2Burn listed on their website (charbroil.com). I note that at one time Coleman used to sell a product by the same name (I saw this on Amazon but it is no longer available). I think I saw somewhere that Walmart carries them too.
I am going to put several of these in my BOB.
