I have tried a lot of feeders and my favorite it Dr. JB's Clean Feeder, it is super easy to clean, the glass jar container sits flat for easy filling, and all parts can go in the dishwasher.

I found the Humzinger spills if it is windy, and I think the hummers drink the water in the mote,
tiny wasps and flies still manage to crawl in and drown as with most feeders.
