I throw in my thoughts, but you will probably get a different answer from each person.
I have used "scents" many times (wasted a lot of $$ IMO) for a long time I used the tinks 69, since I was convinced it was the best (marketing). My observations I have seen, combined with how I used scents to catch coyotes. I have seen the tinks and other doe pee' s actually alarm other doe, I think it is because they pretty much know every doe in the are and their scent, the doe pee i brought in is "doe p" but foreign.
I personally haven't ever had a big mature buck come in to what I was certain was a result of the doe P, but we all know more goes on than what we see, so that doesn't really say much.
Best luck I ever had was with some cheap knock off I got on discount at walmart one time, stuff actually smelled like a cheap cologne, no lie. I almost didn't use it for that reason, in fact I didn't until I ran out of the tinks. I put the "cologne" out one am and had 6 (young) bucks nearly run my stand over. I had so little faith in it, I had just dumped it about 3' high in cedars around my stand, go figure.
FWIW, I always use the hanging scent bottles, or way back, I used 35mm film canisters full of cotton. I don't believe you want an attractant out when you are not there to take advantage of it. I also believe you can use it too often and at the wrong time, which IMO, is a "heads up to a smart buck.
Most interest I have seen, has been just before the rut and during those 1st few days, similar to rattling for me.
IMO, best used as part of an overall plan, not the remedy.
OH almost forgot. I have taken actual doe P from does killed on opening day, same as I have done for coyote trapping. I had does actually smell it rather than running off, hence my opine about a foreign doe P. This may have no bearing on a buck though IDK.
I also know several fellas (one in particular) that spend a fortune on it each year and have nothing really to show for it. I'd use it as part of a plan, but wouldn't stake a hunt on it.
