The flexibility to use different types of gas canisters is intriguing, but in my mind having to use two canisters negates the entire point. Might as well just carry two single burner stoves. For lightweight car camping, I've had good results from a basic Coleman "fold and go" two burner which is cheaper, lighter and smaller than this. Although it can't run on isobutane, propane is cheaper and more widely available anyway, and works better in the cold. I actually refill mine off my grill tank with a simple adapter (technically not supposed too...) Only reason I can see to run isobutane on a camp stove is to use up old half empty canisters you don't want to throw in a backpack.
