Title: Beautiful but useless
Review: Sadly, this beautiful product is too difficult to use. Vaccum, schmackum. It's a pain. In order to create a vacuum you must fill the glass with over 2 cups of sugar water. The hummingbirds need to be the size of elephants to go through that much solution. In the heat of the summer more sugar water gets thrown out (or drips out if you can't get the stopper placed quite right) than can be used by the birds. And if you stuggle with the stopper while filling the feeder all that sugar water ends up on your kitchen floor. Ugh.
