I've never used it until this year and have had deer pretty close. I've used scent sprays, soap, etc. I did buy a Scentlok leafy suit this year and have to say I love it. It was a little pricey but I like all of the features. Pockets, 3D leafs, bow arm guard, etc. I didn't get out much this year but when I did I had deer right under me and I was only 8' to 10' up once and 12' the other times and I didn't use any other scent supprescent. So far I have to say its the best camo I've had and seems to work. I also believe you can do just fine without scent suits. Myself, I will happily use them when I can.
