I just got one from my granddaughter and I'm going to put it out this week. I will use active scrape in it and use just like my regular scrape drippers. In the instructions it states the liquid will last for 10 days. Also you can set it for dawn and dusk or for every 20mins. good luck deerman
I actually just bought one last week and put it out Saturday w/ 2 oz of Tinks buck urine (was cheaper than Code Blues) and put a camera at it. Set at the dawn only option this should last approx. 16-17 days. I'll check it than.
