I love the scent wafers, I have the buck rut, doe estus and earth scent. I use them everytime out hunting. I put one of the earth scent in my bow case and usually pin one on my hat when hunting. I usually hang a couple of buck rut and doe estrus around my stand. alot of the deer that comes my way doesn't seem to get spook by it, actually I think they like it and usually stay around for a while. Like some have mention,itlast a long time, I'm still on my first set I bought three years ago.
