I've not had luck with scents that I am aware of.  I may not use them properly, etc. but I now prefer to skip them.

I have never..ever...ever...shot a deer over scent. I had just about given up on them until some provinces banned the use of them (which is usually the best indication that they work). But I don't plan to buy any again.

I've spent a small fortune on gadgets and gizmos over the years; some were useful - most weren't.

My advice...do your scouting... Pick a spot where there is clear evidence of deer activity (the more recent the better), keep the wind in your face and SIT STILL!!!
