I have been hunting with the pop up blinds since they have came out. I have taken deer, bear and hogs from them and even a lone coyote. I as well leave the mesh up, taken off and left at home for main window, kept the sides to watch out. I only leave the main window partially down, not all the way. I don't open the back window/door. I only crack the sides open enough to see out for I sit in the back against the wall on a folding bag lawn chair with the ground cleared out of debris. I sit all day for gun deer season with my Mr. Heater in front of me and my backpack next to me. Pistol on the backpack, M/L leaned into the front right corner, shooting stick on my lap, already set for a basically predetermined shot height. Works great.
