I use a smaller Texas Hunter hanging feeder. Last summer was the first time coons had raided it. It's my own fault, based on the placement of the feeder. The coon figured out how to stand in the right spot (as they always do) so he could reach the spinner plate and knock feed into his paws. I think the larger stationary feeders are built a little different than that, which might make this type of 'robbery' very difficult. But I've had great success with this little feeder and it has been working well for me the past 5 yrs. Only replaced the battery last year for the first time.
DrLuke, sounds like this type of feeder is easier on batteries. I'm lucky to get 2 years on mine.
I did put a solar trickle charger on it (the one TH sells) and that probably helps. Also, I typically only feed 3-4 sec throws twice a day, when I feed (~ May to Sept, depending on water temp), so lower power use too.
