I have two brands, both worked well. Of course after tuning in on the Pond Pros and Purina I need to start throwing some by hand in another area. I have always both hand fed and feeder but unfortunately got in the habit of doing it in one location and watched it go from fathead feeding frenzy, to bluegill frenzy and now catfish...so I think I will setup both feeders on different times at two opposite locations. Small feed does seem to jam as like any feed you get crumbles and stuff so you do need to clean them out ever so often.
