I did this exact same thing 3 years ago. Turns out it stopped one of my biggest bucks to date. He stuck his nose directly in the film canister. Did it attract him? I can't say that but it definetly stopped him for a good shot and I think thats all scents are really expected to do.

I have also had deer pay no attention to the Tink's. I tried Golden esterous last year on recommendation from other hunters who have had great success with it. Bottom line,scents won't work magic all the time. But it may give you the edge if the right buck comes along.
