I've got the Portable Buddy Heater, bought it anticipating cold temperatures on a few of our off-season camping trips. Used in temps as low as 6F inside the 8 man tent and it kept all 4 of us comfortably warm. We had the windows closed but the top of the tent is mesh under the rain fly, so even with (likely a lot of) heat escaping, we all slept well through the night, except when the 1lb bottles emptied and had to be changed when the frigid cold woke me to remind me the heater was out of fuel. Absolutely would recommend, especially when on sale!
