Review on Set of 4 Gray Bunny Mini Hummingbird Feeders with Hanging Wires - Transparent Humming Bird Feeder Set by Kristin Morris

I bought these after reading reviews that they didn't leak. Well they work, but not as much as the ones I replaced. I only fill them 2/3 full and when I hang them they drip for a few minutes then almost seem to stop but they continue for a bit I don't know why as the flower has tipped upwards. The prickly ones love them and feed them often so I take care of that, I just put a bowl weighted down with stones to keep the sugar off the patio. Would love to find these little ones that don't actually leak, any suggestions
