WindowAlert Leaf Medley Anti-Collision Decals, UV Reflective Window Clings

I have a bay window with 2 feeders nearby. I was getting frequent window strikes and a few years ago a hungry hawk swooping in for a small bird actually broke one of the four panes! (he was fine and I was out $200). I used this product before and realized two things- you have to be generous and install enough (in my case 4 stickers per pane so 16) AND they need to be replaced every so often because the holographic effect fades in time. These are super easy to install. Peel and stick, smooth out with a rag, make sure the holographic side is facing out. (You will know it is backwards when the edges peel up a little) They must be applied on the outside of the clean window. They adhere better in heat/sun, but if its a cold day, using a hair dryer and a rag to smooth them out works well. Since application- zero bird strikes. Not one. These are well worth the money. (If you buy cheaper, you may be tortured with difficult to peel stickers). They are not that visible from the street and have attractive designs. They are easy to peel off and move if you need to correct position months after installation. After time, (2 years in direct sun in my case) they peel off but the design is visible due to dirt and sun. You will need a bit of elbow grease and rubbing alcohol to remove the design off the glass, but no permanent marking is left. Buy enough and space them out about six inches starting at bird eye level. They work and they are top quality. Well worth it.

These stickers made a drastic difference in the number of bird strikes. I would have at least one strike a day, sometimes more unfortunately even causing deaths. After I stick those to windows with frequent strikes, I get none. Also they're almost invisible to us and have an esthetic look if your eyes catches them. They are a little pricey but I sure will buy them next year as well.

We’re pleased with how these work keeping birds from flying into our windows. They also look nice from inside. However we did underestimate how many we needed to adequately cover our windows. Being there are just 4 or 5 clings per packet & some are quite small. I would suggest ordering at least double of what you think you’ll need, or measuring out first. It takes a lot to adequately cover an average size picture window. Even our smaller windows take at least 6 to adequately cover them. But overall we’re very pleased with the clings. We ordered some snowflakes (4 per packet) & some pine cones (5 per pack). My only suggestion would be to include more per package.

These really work! I have a large window at work, and had a couple of birds hit the window😢. Bought these, and no more bird accidents! I’ve bought mote for the other large windows now!

Seems to do the trick and appear to be of decent quality. They peeled and applied nicely as well, and look pleasing in a latent manner. The instructions say these need to be replaced every 4 months as the UV emitting component will break down.. gasp!

These decals are excellent, 10/10, we greatly appreciate how you barely see them-visibility for humans is the most minimal. I feel so much better with these on our windows. Since they are a static clinging decals, they are easy to put on and remove. I washed my windows with sal suds, they adhere without issue. It comes with an applicator/removal tool and a uv flashlight-very official! A worthy note: the starter pack is delivered in 3 envelopes, not 12. I thought i was shorted and reached out to product support. The kind person sent me most of the remaining envelopes; however, what I was sent still did not account for 12 so I reached out again. I was then kindly informed that, to reduce packaging, they have put their 12 envelopes into 3. I felt so bad, they were so kind and understanding about my misunderstanding and my inadvertent theft. I highly recommend this seller and these decals!!

The decals themselves are effective and easy to place on a clean window once you finally get them removed from the sheets. One of the problems is the difficulty in removing the sheet of decals from the attached paper. A bigger issue is that the decals are not all cut enough to remove easily from their plastic binding. This became a bit frustrating and time consuming.

This product works . I haven’t had any birds fly into my windows.

Fáciles de colocar y ayudan a evitar golpes con las puertas de vidrio

Effectivement les feuilles sont transparentes pour l'œil humain. Elles sont aussi facilement repositionnables. Bon produit !

Casi no se notan en las ventanas muy funcionales

ノリで貼り付けていないので、何度も貼り替えが出来るのが良かった。 窓の外を眺めても、透明なので視界を遮る事がない。 今の所鳥もぶつかっていないので、大満足。

Les stickers sont de bonnes qualité, ils sont discrets et un tout petit peu visible à l’œil nu mais ça ne gêne absolument pas pour voir par les fenêtres, et à force on ne les voit plus. Je n’ai plus d’oiseau qui se cogne dans mes baies vitrées. Les dessins sont sympa et facile à mélanger pour un rendu harmonieux.
