I got one as a gift but I haven't slept in it yet. I set it up in the backyard once and it didn't really excite me. You have to wiggle in from the front if I remember correctly and there was barely enough room (6'5" and 210lbs). Set up was pretty easy as long as you followed the directions though there were a number of guylines springing out from it that annoyed me.
Plus side, good ventilation.
Note: I'm not the best person to review a tent as tents generally annoy me.
