Query: attractive and easy to use

I liked the feeder as soon as I unpacked it - it didn't take too long for the birds to like it as well (probably because of the "endless" supply). Where I live, it's mourning doves, finches, sparrows, and the occasional junco.After a few re-fills, I finally noticed the "button" on the top of the feeder to move the top up and down - open it for filling, and closing it before hanging it up. Much easier to use after I noticed that.My only problem - buy one more or two . . .
