Great for certain applications
Fully seam-sealed, this tent is light and packable and ideal for certain conditions: it should be cold and dry to prevent excessive condensation (like many single-wall tents), and you should be friends with your tent-mate, since it is tight in there!
In warm / wet -- condensation becomes a serious issue and you will get wet inside.
Pluses -- Light, simple, packable
Minuses -- condensation, the need to seam seal the whole tent at home (takes 1-2 hours and some care), the vestibule which is overly complex and really a pain to attach.
