A guy I hunt with used Tinks scents last year on his boots and he had a big 10 point follow him right to his stand. As soon as he got situated he looked down and the buck was staring him right in the eyes. He had to shoot him with his muzzleloading pistol because he couldnt get his real gun up to shoot with.

So I think scents work, it just depends on how and when you use them.
