These hummingbird feeders are so cute and different. I wanted to replace some hard-to-clean feeders with something more unique.  It took a bit for the hummingbirds to adjust, but now they feed all day long.  I even hung a little hummingbird swing next to one of them.  They will rest there for a bit between feedings.  These are also super easy to hang.  You only need one screw and they will hang flush against any flat surface.  I highly recommend these feeders.
