>do they keep you warm too or are they just for cooking?
It's 6in by 6in. It'll keep you as warm as you'd imagine a 6x6 fire would. They're mostly for boiling water or light cooking. Twig burners are pretty good at boiling water and take up less space than a fuel canister and burner. But you're going to need to bring something to start the fire and you'll need to gather the twigs. So, it's a bit more effort if you're backpacking and you've been hiking all day. Also, if you happen to be in an area where there are no twigs or it's super moist they're not a good option.

>What's the advantage over a regular fire?
It's relatively self contained. So if you're in an area or under conditions where a regular fire would be impractical, unsafe or illegal, you can still use one of these to do some light cooking.
