No, I dont have any experience with automatic feeders. The purpose of the auto feeders as I understand it is to kick out a certain amount of food at a certain time. This is supposed to get the animal you want to hunt/observe coming to the feeder at a certain time {that you set.} The guys I know that have them say it's not that simple. A lot of other animals eat the same things but they are not all as aggressive as some. What I have seen from my feeders is that just about everything will run deer off, especially squirrels and turkeys. So, the timed feeding dont work too good. I use PVC pipe "corn trees" they are cheap, no batteries {gravity feed} and the animals really use them, They do a better job of keeping game around because they can eat whenever they're not challenged and eat anytime they want. In areas where there are not a lot of animals to run the deer off they will very typically hit the feeders at dawn and dusk. They work as good and sometimes better in the woods as they do in a field or food plot.
