I'll use this for bowhunting whitetails on a food plot instead of pop up tent style blind. Even with the most of the windows closed I'm getting seen. I'm hoping this blind will be dark enough and the window design will be better.  Do you have one of these? Would you buy another? Do you like the window design? Has it been durable? Is it easy enough to remove the blind itself and put it back on the frame? Would it help if I elevated it say 8'? Thanks for the help.
