I have had my Perky Pet Birdscapes Window Feeder for a few days now. I wanted to wait a bit on my review to be sure I was going to love it as much as I did upon removing it from its box. I definitely do and it did not take but a few hours for the birds to find it and begin using it. I have not had any issue with it staying on my glass window patio door and it has not fallen down as I expected it might when I first put it up. It has a nice overhang on top as part of the plastic roofing that helps protect the birds from rain a bit as well as the seeds from getting wet.
