Nice tent but wish the zippers were different
I've been able to use the tent on one trip for four nights. This is my first big agnes tent and I purchased it because it is similar in dimensions to a 4P mountain hardware tent that had been used to death. Prior to this trip, I was stoked for its tall peak height and that it had the same overall dimensions but weighed less than my old tent. I live in the eastern united states with LOTS of mosquitos and found the mesh door zipper geometry and rainfly zippers awkward, slow and requiring two hands for operation. The vestibule wall is pretty steep so it's hard to get your feet out, get out, rezip tent and open the vestibule in one smooth motion to prevent mosquitos from bombing in. I started out solo and had two friends join - it slept the three of us quite comfortably with head/feet oriented between the doors.

Has lasted many years
We used this tent for years as a family backpacking tent. Now that the kids are grown, it is our car-camping tent. It has held up well over the years. Love that I can stand up (I'm 5'2") in the tent.

Backcountry palace
We've had this tent for 4 years and love it. As a family of 4, we all want to sleep in the same tent backpacking. This tent feels like a backcountry palace. It has lots of great headroom, two large doors to enter/exit, and the gear storage options are great for a lightweight tent. We opted to add on some extra gear lofts that Big Agnes sells to keep extra organized. It has taken rain and wind very well. It's very lightweight. No issues with condensation. The fabric is very durable even after kids bouncing off the walls. If we could change some things there's one side that slopes more dramatically down at the base where you sleep (by design). The person that sleeps here is more likely to make contact with the tent side with a shoulder due to the slope. The vestibules are a nice size but the option to use hiking poles to make a little sitting area just doesn't work that well in practice. Not a big deal since we don't use it that way much. The carry bag is somehow less durable than the actual tent so it didn't last long. Easily replaced though. We are very happy with this tent and would buy again and again.

Windproof
Good even in heavy wind. 25 m/s without a problem (without using extra guylines).
