CRMADA 16 Pieces Circle Window Clings - Anti-Collision Window Decals to Save Birds from Window Collisions,Non Adhesive Prismatic Vinyl Window Clings, Rainbow Stickers …

I was struggling with finding something to help the birds in my yard. They'd fly around the house, and see through my picture window to the front window, and fly into it. Several birds died, and others were injured. I put about 6 of these decals on my picture window, and haven't had a bird strike since. The rainbow colors give off enough of a prism of light to guide them around it, is my guess. Definitely worth your money if you've had this issue.

Before installing these clings, we had a fair number of birds who flew into the window, crashing to the porch (and often dying).Since installing these clings, there haven't been any birds crashing into the window. The clings protect the window, and more important, protect the birds from harm. We get to enjoy the birds that come to our feeders, and they get to have a safe spot to eat. A win-win!The clings are clear with a stained glass effect. Each "stained glass" section produces a rainbow effect that is not unattractive.

There's a reason the reviews on this are very high. Just an excellent product and I have compared to cheaper versions. You will be very pleased with this.

I got these for my classroom when I was a teacher and they helped bring some beauty to the room very pretty. thank you!

Works sometime but not all the time, birds still hit windows...

We have a lot of birds on our property and these clings really do help prevent window strikes- I highly recommend them!

I got these after a bird flew in to my sliding door. The bird was fine, but I was traumatized. About half of these fall off. I clean and reapply and they fall off. There were lots in the package, so even with half of them not working, there was enough for my sliding glass door.

I ordered these for all of our back facing windows, since we were getting a few birds hitting those windows. Since putting these on, we haven't had anymore bird strikes! They worked!
