Familiarity: I've used it several times
I put this tent through a variety of conditions over a week long trip to Washington this June for its first use. As such, it was used at slightly lower elevations/temperatures/conditions than I would say it was designed for. It was also used on Ptarmigan Ridge on Mt. Rainier for 2 nights.
In general, I am happy with the performance of tent on Rainier. It was light and compact and more than enough room for 2 people. The initial setup takes some getting used to, but I can recognize the utility of just crawling inside when it's storming to finish assembling the poles. A little tricky to do while windy (took 2 people). We had a pretty windy night at 10.3k and it handled it with ease. No fresh snow to deal with on this trip though so I can't comment on that aspect.
The guyline adjustment from inside the tent is a really cool feature. With both vents and the door slightly open we didn't have any condensation issues up high. At other times on our trip it would get a little damp in the morning but that's too be expected. It was definitely acceptable.
For the cost/weight/construction I'd definitely recommend this tent to others.
