Hummingbird Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Alert Bird Deterrent, Stop Birds Flying into Windows, Set of 20

I love these decals! We were having a huge problem with bird strikes on the windows of our new home, these did the trick! They are beautiful and easy to apply. I have removed them to clean windows and reapplied and after three years only a couple have failed. I highly recommend these.

Unattractive.. did not stick on window.I’ve returned, now waiting for my refund.

These are great to reduce bird strike on your windows since application we don’t hear that bang on the window further prism effect when the sun is lower we get great prism effects into the living room that makes interesting photos we get the window protection year round and a prism showpretty cool product

Hard to get screen off but they stick pretty good. Has helped a little to prevent birds from hitting window.

I bought these as a second purchase for our sliding doors to deter the birds from crashing into them. They work great, easy to apply and others we have been on for about five years. I wash our windows with a wet Norwex cloth, just water, and all of them have stayed intact. Great invention! It hurts my heart when birds crash and die. These decals have stopped that from happening. and I love the rainbow effect!
