Birdious has made a cute bird feeder that has made my daughter extremely happy. I need a hummingbird feeder next! This was so easy to put together and stick to the window. She is so happy watching the birds come up to the window. I love this clear window bird feeder! So interesting to see all the different birds around. So far it has also stayed attached to my window. I am also glad it comes with an extra set of suction cups. I would definitely purchase this product again and woudl recommend to others. I received this product for free in exchange for my complete and honest review.
