Hello campers (sorry couldn't resist), I have to decide pdq whether to buy one or not. Have researched and read reviews but it will cost me 60 bloomin quid and am wavering. Anyone got one, or used one? Am I just falling for good marketing or are they as brilliant as they seem? My main problem is teenage friend of DS is camping with us and he is vegetarian. I am stressing about trying to cook separate food for people at same time..... any comments gratefully received
