Butterfly Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Awareness Stickers, Stop Birds Flying into Windows, Set of 20

They are cute. Easy to put up. When the sun hits them they make rainbows and most importantly keep birds from slamming against the windows.

I have a side porch with tons of bird visitors since we have several feeders for them. We have had so many birds crash into our windows I decided to put up window clings. Really hated the first ones I put up because they were very colorful and too noticeable. These are shimmery and not as noticeable but definitely keep the birds from hurting themselves! Also when the sun hits them just right it casts a "rainbow" into the family room!

Since installing these, I haven’t had a single bird strike the glass doors. My only complaint is that some of the decals didn’t stick well and fell off. I haven’t been able to re-stick those that fell.

So cute!!! A little tricky to get the backing off but really easy to apply+remove.Also thought this would be a pack of five as I didn't read the name, so was pleasantly surprised to see I received so many! Makes them a really good deal for the price

New large windows put in and the birds were crashing, some making it and some not. I put these stickers up and I’ve not seen nor heard one bird hit the windows! Been on for a week and holding up in rain and direct sunlight. Very pleased!

These look nice and seem to help avoid bird strikes, but some have peeled off in less than a year. That might be in part due to the dry New Mexico heat.

Do not work nor cling to the window keep falling off

At first, I didn't think these were going to look crystalized. I used them on my front storm door and at first was a little disappointed. The following day, I walked by and wow, they were gorgeous. I supposed they had to settle in after being put up, which was super easy, but now, they are just beautiful. Well worth the money.
