I have had a traditional two sided feeder that I took down and replaced with this platform feeder. I had difficulty with the two sided feeder not being large enough to enable nuts and fruit to get through. These nuts and fruit are mostly in the waste free blends. But the waste free was wasted in the two sided feeder because it would go moldy. In the platform feeder I put a half a cup a day. It is eaten by nightfall and is truly no waste. I wish I had gotten the larger feeder.
