I use this outdoors with a propane burner with coarse ground coffee. Just set the burner on high until the water  begins to boil and turn the gas down so it perks every 2 to 3 seconds. 5 minutes later you have a hot cup of coffee that is as good as any auto electric coffee maker. Note if you use coffee from a can (automatic or drip grind) you will want filters, that is unless you don't mind chewing it some. Having your own grinder set for coarse ground coffee fixes that and makes the filter optional.

Pros: Stainless Steel
Cons: It is like driving a stick shift on a hill start. Got to pay attention to what you are doing for good results.
