This product is made from steel and seems aweful heavy. I imagine I would use something like this as an emergency backup incase I ran out of canister fuel and would want this to be part of my weight gear list. Unless other massdroppers are planning on using this as a car camping item, I would suggest a lighter version (8.5 grams) found on Amazon:

Buttonpresser@Buttonpresser - as the text in the drop page states, this device is recommended for using your backpacking stove for car camping. To take this backpacking would only add a few ounces, but the weight of the propane canisters would add pounds.
