Query: Great! Simple, mess-free, no ants, and the birds love it.

Within ONE HOUR of hanging this - our first hummingbird feeder, so new to the birds - we had our first visit. In the ensuing several days, there's been a steady stream of birds to the feeder.Note that we are using ordinary, home-made sugar-water nectar; simple recipe included with the feeder, and it stores well in the fridge.
