Review on 🦋 21 Glass Window Butterfly Clings for Preventing Bird Strikes, Anti Collision Window Stickers Decor, Decorative Window Decals for Sliding Glass Doors by Gail Rogers

I bought these to keep birds from hitting my new sliders. I had to put them on the outside of the windows because I have a lot of low-e coatings and darker tinted windows which makes them very reflective on the outside (you couldn't really see the decals on the outside if they were on the inside). doors). This is life size and I only needed two for each glass slider. I placed them where the birds usually attack. I watched the dove almost fly in through the door, but then turned left when I saw the butterflies. Mission accomplished! You don't need many of these to prevent bird strikes (unless you like the look of them). I ordered the larger ones from another company and they looked like they were more for kids - too big for my liking so I ordered these instead and am very satisfied.
