Have only had them in the field for a few weeks, but I purchased two stand and fills from a newer company called Outdoor Addiction. Made in Brazoria off a galvanized cube design similar to Lamco, All Seasons, etc. Not as polished at those brands, but also not as expensive. Feeder was $499 and includes a timer, 12v battery, solar panel, all internal wiring, 12v motor and galvanized plate below the spinner to varmint proof without the need for a cage. I have them placed in the middle of 16x16 pens and about 25% of the corn makes it outside the pen when it throws. You could also cheat it closer to the edge if you wanted more thrown outside the pen.
