Query: Disappointing to birds and humans

I agree that the birds have great difficulty retrieving seed from this feeder. I contacted the seller and they advised using only black oil sunflower seed. That is what I am using. With my old feeder, I had to refill several times a week. I filled this one several weeks ago and only had to refill yesterday. The birds land on it, try fruitlessly to get a seed, then leave. I'm losing my birds to the neighbors. Also, I find it difficult to fill. It has to be hanging to do so. I have my feeders hanging high to prevent squirrel and chipmunk access. I usually fill my feeders straight from the bag. Well it is a little difficult to lift a 25 lb. bag of feed above my head. So I have to use a scoop. Annoying.
