I tend to agree with the 2 posts over mine. I'm sure the double bull is great but I have 4 pop ups & all do the job & stay out all season (4&1/2months here) with no bad repercusions. 2 doghouses, a hunters view lodge & the newest a Yukon tracks commander. I took deer from every one this fall & 2 turkeys from one. The birds are real easy from a blind if they come by. Deer can be spookier but once the blinds there awhile they pay it no mind. I paid way under $400 for 4 blinds that keep me dry all season & cant see that being a dumb move. I'v got one hub style as well but havent used it yet.
