Well, I have been reading a lot about them. I would never use it during a firearm season, bow only and from a tree stand. Some guys say use a buck because does get mad seeing another doe in their area, where they are use to seeing different bucks. Others say use a doe to attract the bucks. One guy said that almost every buck that does see it comes for a closer look. Like I said, I have read a lot and most of it sounds good. I would only use it in the early stages of the rut when hunting near ag fields where deer could see it for 200-300 yards away. Every year you hear a story about a buck that crashes though a window because they saw their reflection or a concrete deer getting mounted or attacked by a buck. That makes me think that in the right situation, it may work wonders.
