YMMV - It depends and that applies to every single scent eliminator and I've used quite a few. If you're hunting from a tree stand and it took very little effort to get to it and into it you'll probably see good results with any good cover scent/eliminator. If you just did the kind of hunting I just did in Montana where you climb 1000-3000 vertical EVERY day there is no way to eliminate all odor because you're generating stink and sweat and you really rely on wind direction.. I still use cover scents and eliminators because I feel they help, but they aren't magic. Chuck Adam's subscribes to a similar philosophy.
