Large Cross Star Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Awareness Stickers, Stop Birds Flying into Windows, Set of 18

The only comment I have about this product versus others like them is that if you don't have fingernails or patience, peeling the backing off of the star will frustrate you. A straight pin does work to start the peel back and then it's easy from there. Be sure that your windows are clean and go back over the stars with your dry cloth after you put them up to get the air bubbles out. They are delicate but if you take your time, they go on well. Each design comes in a small plastic bag rather than on a sheet of paper that other clings come on.

Update: I've had these a year now, and they did their job of preventing bird strikes. There were no more strikes once I put these up. Very pleased.I've only had them up a few days so far, so waiting to see if they suit their intended purpose, but in the meantime, they are lovely in the window! Nice and thick plastic with beautiful prisms when the light shines through. I think these are the prettiest of the designs I've seen of similar products. Easy installation.

These clings work great - a few of them are a little tricky to remove the backing in order to apply, but it's a small price to pay for how well they work. I was a little worried how they would look (I applied them floor to ceiling on sliding glass doors) but the safety of birds comes first. So I was very pleased that they lend a nice "starburst" MCM effect on the windows, while keeping the birds away.

At first I couldn't figure out how to get the backing off. Put a piece of tape on each side and then pull tape off up in one direction and pull the tape down on the other side. Backing came off easily. Not an eyesore Very happy with this product.

Cannot prove they work to prevent birds flying into my windows, but no birds have flown into the windows since I put them up. For the price it has been worth trying. They have held on well. Have not tried to remove one yet.

So far so good. I have to say not a single bird has struck the window. They are not a hinderius when viewing out the window. They were easy to apply. I haven’t had to remove them so I can’t say how that goes.

Great for my plate-glass windows to deter birds and add rainbow effects when the sun shines through them. They stick easily with water; follow the tips to use a piece of tape to separate the backing.

I applied these decals three time to my window - it's not easy since the window is in my vaulted entry. They do not stay on more than an hour. They fall off the windows and yes, I followed the directions to the 't'. They are lovely but they don't work. What a waste of money and time...
