I've used one for bear hunting in Mich. U.P. Because of the window placement, I had to use the door as a shooting port for my longbow, because the window bottom was too high. Worked fine and had bears come within 5 feet of the blind. One year the bears were only coming in to the bait after dark, so I took to taking the bait with me when I left at sundown. Apparently one of the bears took exception to it and tore my blind up the first night and tossed it about 20yrds away and snapped one of the aluminum struts.
