Ring and Circle Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Awareness Stickers, Stop Birds Flying into Windows, Set of 21

These decals work great. Our windows used to get bird hits all the time but not anymore. And the varied sizes of circles and rings look pretty in the sunlight -- they're not as distracting as some other patterns that look too blocky. They've stayed in place on the windows for almost one year now -- even through the winter storms.

These seem to be working! We have not had a single bird mishap since putting the decals on our sliding glass doors. You do not need as many decals as they give you, but you could share them with other bird lovers. The decals do not bother the view and I caught a really cool picture!

The decals seem to stick well when sprayed with water but didn't really think about the drying time needed for them to be REALLY stuck! About 30-40 min. after applying we had a storm roll through and later on I noticed all of the decals on the upper windows were resting at the base of the window frame, doh! I will say I did have to spray more water on them to get them to release, so once they've had a chance to dry well I'm pretty confident they'll stay put....we shall see, it's raining again right now and so far they're all still in their original position! Getting the backing off was a MAJOR headache, as others have mentioned.... I tried the recommended scotch tape technique but had moved on to sticking on two pieces of stronger packing tape then pull in different directions but it still took many, many tries to get the backing off:( Hopefully these reflective pieces along with the white reinforcement labels we already had up will do the trick in avoiding any future collisions!

I bought these for my big window about a year ago because poor birdies kept flying into the window and I couldn't bare watching another bird get hurt like that. These WORK! I haven't had a single bird fly into the window since then. They were super easy to put on the window and they have stayed put through extreme heat, extreme cold and lots of storms. I highly recommend.

These are perfect. My daughter has had them on her window a few years now and they still look great! Easy to put on. Visible even outside. Beautiful with the light shining through them.

Do not buy these. They do not stick to glass no matter what you do. Choose another brand for something functional.

Unfortunately, these did not work for me. It’s of no fault of the product. The decals can be applied very easily and stay securely fastened to the window. However, I did not do my full research prior to purchase. Anything applied to a window to keep birds from hitting it must be approximately 4” apart. I would have had to apply hundreds of these to my windows in order for them to be effective. If you have a very small window to address, this is the product for you.

Put on windows to stop birds from crashing into our windows. These windows face the woods and so the reflection is misleading to the birds I think they have been up for at least 3 years and so far so good. I haven't had any fatalities. Have had 1 fall off and some are getting dirty.

Finally! A bird strike deterrent that looks amazing, not tacky. These blend in yet really shine when the sun hits them, causing little rainbows everywhere. Peel and stick ( no adhesive) Love them And no more bird strikes….

The product arrived quickly & installed well when I followed instructions to remove the backing on each decal with 2 pieces of tape and mount on a wet surface (used a spray bottle). At this point, I gave 4 stars b/c they've only been up for a couple of days and I dk, yet, how well they work as a bird deterrent nor do I know how long the decals will stay mounted (i.e., will they last throughout the Canadian winter?).

The dotted lines for each circles are printed on the circles themselves, which you can then easily see once installed. Does not come with instructions either. I recommend buying from another vendor/supplier

These window decals, stay on very well and let a lot of interesting light into the room. The only reason I gave a 4 and not a 5, is due to the fact that they appear to be coming from Ireland, not Nova Scotia. I was hoping to support a company more local to me. Otherwise a great product.
