This is my first foray into hummingbird world, so I looked at all the reviews before I bought this one. I did the rubber band thing as one reviewer suggested and so far, no detectable leaks. The bright red color and nectar should attract some hummingbirds, I hope.  As far as the plastic parts, I will see how long they last and post an update at a later time. This product was well packaged and arrived on time.
