100 Pieces Anti Collision Window Stickers for Birds, Sticker Decals for Windows, Glass Awareness Decals Clings for Bird Strikes, Stop Birds from Hitting Windows, Circle-Style

I have had them over a year now and no more birds hitting my window (knock on wood). The colors from the outside change with the sun and light. Different colors as you walk past. Easy to apply and take off. I am happy with my purchase.UPDATE: Two years later and not one dead bird. Before I had 4-5 a season. These things are great!

Keep the birds from flying in my door and windows nice

As others have mentioned, these are actual stickers and NOT clings. They are great if you don't mind putting actual stickers on your windows but I was looking for static clings that can be removed easily. So the product in and of itself is good but isn't as described in the title of the product.

These have sticky backs and are not easily removed. You can't change their placement on your windows.I was hoping they were the static cling type. These can't be removed and re used.In all fairness, they were not advertised as static cling.

I have a sliding glass door to my backyard and get about 3 hits a week. After putting up discs high and low and in between all over the glass, the hits came even more often. I put them in a drawer. Anyone want them?

THEY WOTKED NO MORE BITD FLYING INTO WINDOW.

I was incredibly apprehensive about sticking these on my window, mostly because I don’t know how easy they will be to remove in the future but they definitely work at keeping birds from flying into my window and having birds fight themselves in the reflection.

I have a lanai with metal shades that come down and there’s a tiny opening they can fly into when the shades are down and they try to make nests. Ever since I bought these I put them hanging halfway so they don’t fly into it and it works!!!!! Oh my gosh I was fighting them off to prevent from nests being made so I can open my shades regularly and now I don’t have to worry about it! It’s been about a year now!
