I tired the VS-1 last year, Paid big for it and deer barely noticed it, I went back to Bob Kirschner's Silver Top and got much better results and my buddy went back to tinks. We even tried a test with it and placed scent canisters in a feild about 50 yards apart upwind from a major trail using Tinks 69, silver top and VS-1 and got only one spike to even show any curiosty in the VS-1, but the the other two both made bucks leave the trail to check out the canisters. I will never waste my money again.
