Strip Anti-Collision Window Clings - Glass Alert Prism Decals - Prevent Birds Strikes – Decorate Your Glass Doors, 50 Pieces, JD018CHANGTIAO

Very easy to install and is definitely working no bird strikes in last month.

Our back yard was turning into a death trap for the poor birds so I was looking for a product that would save the birds but not ruin my picture window looking into the back yard. These strips are exactly as advertised. One thing to note is that they are applied on the outside of the window, not the inside.

This is good and happy to put on windows to save birds from flying into the windows and injuring themselves. Easily transparent and doesn’t take up much space on the window but does the job. Keeps birds safe.

They seem to be working well. I only needed to put up a couple to make them work

Product fails along multiple dimensions. First, it does nothing to stop the birds from hitting my second floor windows. The banging continues unabated. Second, they are not the pretty iridescent prismatic as pictured. My husband thought I had put plain scotch tape on the windows. Really unsightly. And third, after all that that they don’t stay up. The strips started falling after a few days. The only positive thing I can say is that having all of them fall off within a week spared me from having to get the step stool out to remove them.
