I just got back from a trip on Aconcagua and my partner and I used the EV2. It had enough room for the both of us but not our packs; just a small amount of gear and the stove could fit with us. Since there is less volume to take up we were warmer than most people, which is a plus if you dont mind being close to your buddy.
Pros: very light, easy to set up and take down, pretty storm/wind proof if set up right, good amount of interior pockets.
Cons: can be considered small for 2 people, more condensation/frost buildup than most tents, footprint is useless: makes the tent leak on the bottom seams because it stretches them too much, integrated vestibule is indeed useless.
Bottom lines is that the EV2 is a good tent but there are better single wall 2-person tents for that price. The main thing is the tent is very light, so if thats what you want then this is a good tent for that. It wasnt my tent but I would look at the Nemo Tenshi or the Nallo 2/3 GT. In my opinion these tents are better.
