I have had this before camping gazebo set up for about a week now, and in that time we have had strong winds torrential rain sunshine and cool temperatures. So I feel uniquely qualified to review! I will start by saying that I did not anchor this into the ground because I wasn't sure I wanted to keep it where I had set it up. When I first set it up it took less than 5 minutes for me alone to get it standing. I'm a 65-year-old woman in not-great shape. No problems!I did not put the rain cover on when I initially set it up but decided since rain was forecast to add them on. That took about 10 minutes. I made sure to secure the flap above each opening to the rain cover and then make sure each velcro strip was fitted and the handles were securely pulled through the openings. I then made sure that all of the flaps at the base of the tent were pulled outward. I placed a couple of 12 packs of soda along the bottom flap at two sides, then tied two of the pull handles to the kingpin on my RV to be sure it wouldn't blow away. These preparations were more than adequate to keep the tent in place despite heavy rain and 20 to 30 mph gusts that came that evening. I'm pretty sure that the tent would need to be firmly anchored to the ground if winds were sustained, but it held up well for the gusts that we had.Inside the tent we were snug and dry. I laid one inch by 2 ft by 2 ft interlocking foam mats down, a 32x72 table and 5 chairs inside, and still didn't feel cramped. I think this would even work as a sleeping tent in a pinch!This was definitely a great purchase, much better than the 10x10 clamshell tent that I had purchased last year which did not last even one season. I would hardly recommend it to anyone seeking a bug-free shelter for camping or your backyard!
