This is very good at keeping poop out of the seed cups. I have a very large cage that very tall. So, I sometimes want a seed cup on the bottom. This ones works well for that. It can be hard to clean because of the cover.

Pros: keeps seed/water in, keeps poop out

Cons: hard to clean well

I have heard great things about these and plan to get some for my birds. They say that they really do keep food throwers from making such a mess.

Pros: Keeps the seeds from being thrown across the room
