Wont add too much as most people have covered it – got one, it’s great. Only used a few times, but harshest was a few days in the lakes and as long as it’s pitched properly it is as good as you’ll get for a sub kg tent.
We had -3degC, biblical rain and 50mph wind and while it did collapse on the first night that was 100% pitching error – I put it up at 11:30pm in the dark on a gravel carpark and only put the pegs a few cm in – which all pulled out as it softened when where I was pitching ended up being a river. But I still stayed dry!
When windy definitely worth pitching feet into the wind as then the door seems to work best and it doesn’t inflate when you open it, when cold I pitch it a little lower (adjustable pole) to reduce the draft through but this means you end up with a fair bit of condensation – which I was pleasantly surprised that it ran down the material and not onto me.
