I had a feeder like that once. Mine worked great for the first twelve years.

At the beginning of the 13th year I think a screw came loose in my feeder. Suddenly the feeder only wanted to throw feed when it felt like it.

In the 15th year I'm fairly sure that the circuit board had a malfunction. The feeder began rebelling against throwing feed all together. The feeder thought it was smarter than every other feeder. The feeder began questioning my pond management decisions.

At 16 the feeder got some wheels. That's when the feed really hit the fan. Nothing worse than a mobile feeder, you are constantly worried about where the feeder is and what the feeder is up to.

At 17 or so the feeder began bringing home other feeders. Jeez was that a difficult time. Some of the feeders that were brought home you just knew were up to no good.

And expensive, dang, everytime I turned around the feeder needed a new part here and a new accessory there. Nickle and dime you to death.

Course that is just my experience, your results could vary.
