Zippers suck. They break and get stuck. There are way too many vents/holes. Tent is sturdy, but you gotta get those zipper right baby. I'm using those things 5 times a day. Half the time when I try to zip up the fabric gets caught in the teeth and I'm there pulling and cussing for three minutes to fix it. For that reason, I would never buy a Vivosun tent again.
