Ya it works, but it's nothing magical. Deer are not going to come running to it the day you put it out, deer have to find it first, it works no better than corn or any other attractant. Deer hunting is about being in the right spot at the right time, and thats the key, knowing which is the right spot and the right time. Learn that and you will be succesfull.
The stuff you see on TV where they come running to it, is on high fenced over populated hunting preserves. Hunting shows are a gimmick, believe nothing you see on those shows.
