I personally own a ghost blind and yes they work!!! I still choose to brush them in a little and let the mirrors do the rest. I've had deer extremely close and unsuspecting hunters even closer hahaha. The only down sides to this blind is your back side is very exposed, I always cut some branches fill in behind me, also they are really short. I'm only 6' tall but when I sit in my blind on a bucket I have to crouch a little for cover. I guess they sell extenders but I haven't bought any yes. But yes they work and work well when placed right (like anything else).
