What are your expectations in deer scent products?

I've had great luck with code blue buck urine that I spray on my boots b4 walking in and around my stand. I have also used code blue doe estrus gel during rut. Last year I used it on a drag rag and had a decent 4×4 follow my footsteps right to where I hung it in a small tree 20 yards from my stand. I guess in my experience code blue works for me.
