I purchased The One right after it came out. Unfortunately, I’ve only had one opportunity to sleep in it, and that was after snow blowing a patch of ground in my backyard to set it up. Still have snow on the ground now.
The tent pitches easily, is taut, temps were in the 20’s the night I slept out - had no condensation problems. Also had about two inches of snow fall during the night, did cause some sagging, but nothing detrimental. Wouldn’t take it where I was expecting a lot of snow on a regular basis, but it seems it will handle some ok.
Substantial interior room, good head room, able to sit up using some care not to brush the tent immediately above your head, but no contortions needed. I think I will be very happy with this purchase.
