I have use Tinks in the past and have had mixed results. I have had some good deer come in but I don't know if it was because of the tinks. When I would first introduce it to a new area it seemed to work ok. I don't know this to be fact, but, since they have changed from glass to plastic it doesn't seem to work that well for me. I will be switching to a brand that has no preservitives in it this year.
