The main thing I like about this product is the fact that the squirrels are not harmed in any way. They may have to suffer some discomfort with the noise, which I understand sound to them like a jackhammer blasting away net to their ears, but they know to quickly move away to somewhere quieter. Hopefully, that will be somewhere that is not in my house.

What reviewers didn't like

Large size, Non decorative, May not be as effective outdoors.
