Well if your going to invest in a blind .Go with a double bull

.Good heavy shell,big zipper for the door,easy setup took me about 2 mins. getting out of bag till standing.Grab a hub pop it open go inside and start popping the side's out and the roof.Mine is 5' square,5' from the ground to the corners,6' center height.The shoot through netting go's all the way around the outside.You can pull it up if you want to.there are strap's inside so you can adjust your opening height.I left mine the way it came and the window will open about 12".Very dark inside. Has a zippered roof opening.The robs are 3/8" diamater.You can twist the hubs to make the shell tighter if it's loose.Weigh's 21 pounds.Quick take down just push a side in go to the next side do the same thing and it's on the ground.This is money well spent.Pic's to follow.
