Large, easy to set up
Size: 10 Person
Better than anticipated! Loved the size, the ease with which it was put up, and the height! Not a fan of how the "room divider" divides, but it works. Despite the photos, for some reason I was expecting a little more separation, but you have to go through the first 'room' to access the second. Other tents that I looked at that had 2 rooms had 2 side-by-side entrances. Still, very pleased with the tent overall. Did not get to test the water resistance, luckily, but it does seem like a good, sturdy tent that is easy to put up, even with three 7 year old boys running around the camp site.

Easy set up
Size: 10 Person
The tent was easy to set up. The instructions were easy to understand. It was nice to lay out the tent and clip the poles into place. Easy to set up for one person. All the zippers work and looks to be well made. Hopimg it will.last quote a while. I'm 6'3" and had plenty of space to stand. Lots of room on the inside. Looking forward to using this tent a lot.

No Good
Size: 6 Person
Brand new screen netting on door and windows had small holes thus allowing mosquitoes in. Unfortunately the return window passed but due to weather we just got to try it out last week. Also floor had pin holes first use which I think after several uses will develope bigger holes. Very thin material. Also came with no setup instructions but that was easy to figure out. Like the fast setup that’s it. I may have gotten someone else’s return ???
