This is a great tent. I have been putting this tent to use this year and I have had zero issues. I do not have any issues with the top bar getting it to click into place. Make sure you extend the top bar first or you will have issues because it’s harder to reach. This tent is super easy and fast to put up/take down. The room darkening is great on the tent because it blocks the heat of the sun and allows you to sleep a little longer if you want. The fly is very durable and is for sure water proof. You will have condensation buildup on the inside of the fly if using a heater but that is to be expected and it will not drip on you. I have had zero issues with the zipper. The tent is a perfect size for my wife and I with our two dogs. This is my go to tent when traveling because I know it’s not gonna let me down and it fits in any campsite.
