i hear a lot of good things about this attractant. anyone actually use it?

Corn has worked for the last 40 yrs for me very well.

Corn is good. Someone is always trying to make something better.
I have messed with other flavored corns and attractants for fun, it was really a waste of my time.
But I did learn something; whatever feed you use, the deer are coming to the sound of a feeder even if it is throwing rocks.

The only thing I use is the protein blocks. My deer mow through them

I've used the Vita Block and Big & J blocks too with increased buck traffic in the pens when using them.

I have had good success with it away from feeders. I had deer on it within a few hours quite a few times. Also, we didn't have hogs on both places that we tried it. I can see it clearly works and had deer on camera bedding next to the blocks after they kicked them around. I have put it in multiple places with the same result. I believe the scent of the Big and J works better than regular corn and yes corn obviously works. I would put it away from the feeder and put a camera on it and get your own evidence
