Joiedomi 6 PCS Hummingbird FEEDERS Set (2.2 Oz Each) for Bird Lovers, Bird Sanctuary, Park, Backyard, Patio, Garden

Are the hooks and slings included with these or just the red wire and small cleaning tools?

Can anyone recommend the perfect cleaning brush for these?

The last ones leaked like a seive, ever with teflon tape in the threads, are these any better?

Where can I get red replacement flower ports that fit this feeder? The attachment doesn’t fit the easily available replacements.
