The decals appear to be disintegrating. They have marked up all of my window and I am unable to get it off. I have them on my sliding doors and panels next to them. It's the whole length of the window.

Delivered quickly and all good. I bought 2 pieces but are not big enough for the bay window. 3 would be too much.
Arrived quickly and was all correct. One pack of decals was not enough for the large window, but two was plenty.
I found this after looking up how to prevent birds flying into my storm door. It's working, no more birds hurting themselves. After Helene blew through and took down the tree's across from my house I suddenly had birds flying into the door. Would and have recommended this product
I bought a small package for our front window by our bird feeder because every day we would hear birds hitting the window it worked so well that I ordered more to share with my daughter who just moved into a new house.
Always a great product in keeping birds safe.
Window Alert Window Stickers to keep birds from hitting windows work great! Reasonably priced, comes timely and website easy to navigate.
It was great — good price, arrived quickly in working condition. Thanks!
Within 30 minutes a bird hit the windows containing the deflectors.

We'd love the opportunity to work with you to understand the specifics of your setup and explore ways to improve its effectiveness. Your feedback is invaluable in helping us enhance our products and support our mission of reducing bird collisions. Please feel free to reach out to our customer support team at [email protected] so we can assist you further. Thank you for caring about bird safety and for giving us the chance to address this.
Haven't been able to install yet due to weather, but the items were delivered in a timely fashion and are as advertised. Really looking forward to cutting way down on window strikes!
Item came in a timely manner. The decals were just as described by the seller. They were packaged well with helpful instructions on how to use.
The one thing I would suggest is selling your window decals in value packs that cost less. I’m living on social security only, and I have a lot of windows and it gets expensive having to buy so many 4 count packs. I can only afford to do my windows in the front of my house because I have to have 14 decals just for that.
Canada post has been on strike for the past 3 weeks. Consequently they have not arrived.
Delivery was prompt, order was complete, instructions were helpful, and my mother loves the new "decorations" on her window at the memory care facility. And no bird strikes so far!
The Window Alert product does not work at all. The birds continued their attack on our windows within 30 minutes from applying the stickers.
Hi Joel, I am sorry to hear you are unsatisfied with our products. I suspect that because you have birds attacking your windows the appropriate product for you to try is our Stop Bird Attack spray. Please reach our if we can be of further help.
The stickers look nice and we're easy to apply. Would prefer it if they had some designs that were smaller in size with more stickers per sheet.
Great widow decals. Speedy service. Thanks!!!
