This feeder was exactly what I was looking for. The product was improved by making the flower white to cut down on attracting bees. It is the perfect size since humming birds are lone feeders and you do not need many ports since only one will feed at a time. It allows me to buy more and spread them out around the house to cut down on the fighting over a feeder. I had no problem with leakage. It was a great year for my humming birds thanks to this product.
