content: I got this for camping because I was tired of using expensive throw away tanks that didn't hold much gas.This one is a great compact size and costs about [...] to fill up. It is more than 4 times the capacity of the smaller ones yet still costs less to fill up then to buy one of the smaller ones.The only reason I gave it four stars is because of the price (although it will eventually pay for itself). Also sucks that Coleman makes you buy another [...] attachment to attach to their stoves.
