I don't like the product but the sellers did all they could to make it right.
I hang a couple of them to my peach tree and they do scare the deer and squirrels away.
These really worked to keep the birds away from our pool and patio!
They seem to work at keeping other birds away but are Too light for any area that has any degree of wind.
I hung one at the entrance of the garage when the door is open and they work but it's protected from the wind.
Didn't keep the birds away.
The birds and the squirrels are having lots of laughs.
They just hang out with the owls, watching them spin while they enjoy the peaceful sounds of the bells.
Seems my birds have never seen an owl or totally ineffective, placed in my fig tree and birds eat figs next to owl.
You need to hang it high or have a large tree.
