Query: Never worked!

This is a very flimsy feeder. It never worked. It rotated a quarter of the way and would not rotate again. Of course I waited too long to return it. I opened it up hoping to fix it. But I noticed the gears are all plastic and very thin and loose. The gears can get out of alignment very easily, which is why it would work a little bit, then stop working. Worst $20 I ever spent.
