well I have never had any luck with the TR's, for what ever reason my deer don't seem to like them>?
tried off and on a bunch of times over the yrs, and they just don't go near them
NOW I get the cheaper mineral blocks from Tractor supply, like 10 bucks for a 50 lb block
and my deer hammer them
funny how deer from one area to another can be different?

But haven't put a cam over a mineral block since last summer
Guess I will have to move a cam soon LOL
