OK in the rain but not greatAwning over front door is nearly useless (too short)The way the front door leans back (like a pyramid) means rain pours straight down through it when you open it.The rain-flap over the door zippers is floppy enough and thin enough that it gets caught in the zipper... kids are constantly calling for helpIt's spacious. At 6'2 I can stand upright in the center of it, but not elsewhere.The ceiling near the ends of it are pretty low, good for stuffing bags but not really usable space, i.e. it's not really 18' because the last 2-3 feet at each end is so low. We use cots, so this is a more pronounced issue because the higher you are from the ground, the further you have to be from the edges.It can be set up by one person, if you're tall enough. See responses to this review for details.Airflow is great, even zipped up.The foot pan wraps up the side of the tent several inches = good.Several mesh pockets keep glasses, phones, etc from getting stepped on or lost in the dark.You get a lot of space for the price but the zipper is truly a hassle, there's no vestibule, no front canopy worth speaking of, and it's not great in steady rain.PROS: Lots of space for walking around, fantastic air flow, stays up. Price, @130. Value is off the charts.CONS: Entry zippers are a real hassle, zippered vents can't be used at night (dew pours in), no vestibule[EDIT UPDATE JUL 2013]It doesn't really leak, but water gets in nonetheless.The pyramid shape means the 'doors' face partially up toward the sky, so rain comes straight in when the door is open. If you're stuck in a long rain, every time someone goes in or out you can get quite a bit of water in the tentThe zippered vents face even more directly upwards and are even more open to rain. To maximize space, there is a tendency to sleep around the perimeter of the room and that puts people right under the zippered vents. Chances are, you're sound asleep when light rain or dew wets part of your sleeping bag (or your laptop, or your clothes). You pretty much have to keep the vents closed at night unless you don't fear rain (or dew) coming in.You can learn to work the zipper... grab it with middle finger and thumb, use your index finger to hold the flap out of the way. This works 9 times out of 10. The trick is teaching your kid's friends how to do it. Zipper works fine from the inside.Despite the zipper vent issue, there is a lot of air flow coming through the screened area under the rainfly. If you tension the tent carefully using the included cords, you can maximize the airflow at this gap.If you get plenty of tension on the rainfly, use all your velcro loops on the fiberglass poles, you can keep the sidewalls of the tent from drooping in, and shrinking the useable space. If you overtension them, the zipper doors won't want to zip.For the price, it's still a great value, even a dozen camping trips later. If I am expecting terrible wet weather (and we're still camping) I will use my other tent (Coleman ARA 6) but normally I use this one because big=comfortable and even in light rain it's nice to have extra space to keep stuff out of the rain[UPDATE SEPT 2013]I ended up making my own vestibule; I really like having a space outside to put a chair where you can sit to put shoes on without getting wet or tracking muddy shoes into the tent. I bought a Kelty Noah's Tarp 9x9 and some poles to make an awning over the entry. Unfortunately the tarp & poles cost about as much as the whole tent.I got tired of trying to stuff it back in it's small bag, bought a 4'x4' mesh bag (made for storing boat covers) to store the tent. You could also use a 4x4 ball bag for like $5.
