They work. Some individual deer may have prefer one lick over another, but in general they work. I've seen squirrels and skunks licking them.
Two years ago, my dad & I put a molasses flavored mineral block out behind his house (Elmore Co. AL) and the deer found it right away. With the deer licking it and the rain, it lasted just a bout a year. Once it got to 50% oforiginal size,it "grew legs" so to speak and kinda moved a yardor two everyfew nights.
We set out a gamecamera and got some nice shots of ayoung doe and a 3x3 buck. The doe hadfawns withher last season, and the buck is around but they haven't seen him, just his rubs...bigger than before
