Brilliant little heater
New to camping and didn't want to get too cold in September, got this heater, ex display so a few quid off too, but wasn't sure how good it would be during the night. Pleasantly surprised. Kept the chill of the air during the night and occasionally could hear the thermostat kick in, but nothing too loud or annoying. I'm not sure it would keep the tent warm in the middle of winter, I suppose it would depend how big your tent is, ours is 2 rooms, 6 birth. Highly recommended!
