I use a Turboflame Ranger and it works fine. It is refillable butane and I never heard of it until I bought this thing but the instructions say you must use highly refined, zero impurity butane.....and they are right. But, if you fill it properly and use the correct butane it works great, in the rain or snow, wet or dry, wind or calm it lights. Amazon sells these things for $71.00, but I didn't buy mine there and I didn't pay no $71.00 for it either. 3" long, 1 1/2" wide at the widest point and has a hole for a lanyard. As long as I have this I cannot get lost in the woods...just look for the lone single hillbilly standing next to the 40,000 acre forest fire because if I don't know where I am I am burning the woods down!!!!! I wont be lost for long...wont be cold either.
