I am so happy with this purchase. This tent is simply a work of art. It exceeded my expectations in every way. Its construction is top notch, very high quality and the engineering is so thoughtful. The ability to change the airflow configurations (completely close, screen, completely open) is really convenient and easy to do. This thing is going to last a long time. I've had it setup for over 1 month now in a semi sunny spot and there is no sign of any water leaking or mold growth. I'm very happy with this purchase.
