I'm currently using the Olicamp Space Saver Cup. It fits on the bottom of my 32oz Nalgene bottle. I use it with a Coleman F1 Ultralight canister stove. I mostly use it for heating water for coffee/tea, Cup-O-Soup, Instant grits/oatmeal, or freeze dried meals when I'm down on the river bank camping/catfishing. I like the swingout handles and how it saves space because it fits on the bottom of my waterbottle. It stays in my truck in a shoulder pack along with the rest of my gear and I change the water out once a week. I haven't really cooked anything in it other than pouring my soup or grits in it and eating out of it. It works for me.
