I sat in a Primos surround view 270 at Scheels the other day, and it is the most spectacular ground blind I've ever been in. See through walls virtually eliminate blind spots, but looks like a normal blind from the outside. Blacked out vertical windows when closed (we've started painting some of ours black and it really does dramatically reduce the spook factor on deer). I just wasn't ready to give up 4 bills for one, but judging from their lack of availability online, they must be selling pretty well.
