They work, I took 7 from blinds last year & 2 so far this year. 6 of last years deer were 2 at a time. I set them up a couple weeks before the season & only hunt them rainy days until it gets cold. Once theyre used to them the deer pay them no mind. The mesh works fine if your bows tuned well. I'v actually shot thru my blind several times because I was scared to open the windows very far. Shooting thru the blind they still hit theyre mark.
