Big n j or mobucks

I have seen mobucks work killed a 8 last year pored it out got in the stand 30 min later 8 point down and friend did the same but killed a 7 pt off his camp porch..put it out in the corner of the camp yard at 4 pm at 5 he shot it from the porch .must be the molasses they smell and come to it.. I have seen the shows and commercials about bign j but has anyone had any success with it? I don't know how u can get better than calling bucks into the yard in an hour of putting it out.. B n j also cost a lot more than mobucks
