From what I've experienced personally it hasn't hurt my hunting. I usually pull a "drag rag" behind me when walking in / out of my stand location. The deer can probably still smell human scent, but it can't hurt to try and cover it somewhat.

I have also had bucks walk right up to a scent wick with doe estous and smell it. (on several occasions). So I wouldn't say they don't work. Why else would a rutting buck go straight to the wick.

All in all however, the market really does have these products overrated. They may work to some degree, but they are not a necessity.

Hunting downwind is always your best bet for not getting busted.

A bottle of buck urine or doe estrous may help. But I wouldn't go overboard investing a bunch of money in all these scent and scent eliminator products. I use the cheap Code Red Estrous when I do use scent & get a large bottle for like 5 bucks.

When making mock scrapes, I have actually pee'd in them instead of using deer urine.
And it works. Deer started using the very scrapes I pee'd in. May not believe me, but it is true. I have no reason to lie or spread false info.

This is just my personal opinion and experience....
