I had a 4 man and used it for three seasons,plus summer. A lot of people like them but I am not one of them. There was a lot of condensation unless the stove was on. On a sunny day moisture from the ground condenses on the walls and you are greeted with soggy gear. In heavy rain the floorless thing becomes a problem. The slopping walls mean the 4 man is a 2 man.
In cold weather the stove does work well and this is the strong point of the tent. I sold it last year.
