Anti-Collision Window Decals for Bird Strikes - Glass Reminder Bird Tape - Avoid Birds Strikes (Clear-1/2 x 30' x 2)

They work. Tons in the package and they stick thru many Michigan winters

One star only because zero is not an option. Looks terrible and it is NOT easily removed! It took me 4 hours of scraping, dissolving with WD40 and scrubbing to remove it from my windows (after just a couple days after installing).

My feeders attract many birds, and I had birds hitting my sliding glass door at least twice a week. I tried all of the cheap home tricks to no avail. So far I haven't had a birdie accident in the twenty days this has been installed. The instructions say to apply it to the exterior which I did. We have had lots of rain and the tape on the lower half of the door is wanting to lift. If I have to do it again I'll install it on the interior. Also, it's not hard to install but keeping it equal in distance and straight is another matter altogether. lol

Difficult to remove.

Our living room window is large, 4' X 8' and you can look through it to the sliding glass door to our deck. Birds apparently thought the window was a shortcut, and we had many strikes, with many birds dying. I read about many solutions and was about to make one from para-cord when I found this style. My wife and I installed them; I marked the center of the window then pencil marked 4" intervals from the center marks to the left and right of center (top and bottom of the window). She started the top and unrolled and I took the roll mid-way down and unrolled to the bottom, holding the strip away from the window. She cut the strip while I held the strip away from the glass mid-length. She took the bottom end, slightly stretched the strip and I released the middle. Then we gently tapped down with our fingers, the gently rubbed the strip down to the glass. This process reduced or eliminated any wrinkles, and kept the strip straight from top to bottom. We figured this process out as we progressed. We don't even notice the tape anymore and haven't had a strike in the almost 4 weeks since installation. I clean our windows' exterior with a soapy applicator and a silicone squeegee, and don't expect any issues cleaning over the tape.

The product says it’s clear but it’s “clear” like scotch tape. One picture showed it more opaque/clear and one looked white. Collidescape is what I originally purchased but needed more so tried this brand to save a few pennies,.Big mistake. The tape on the right is from Collidescape and on left is from Tis Tiloz. I don’t usually write reviews but wanted to show this photo and you can decide.

I bought the stuff to put on my windows to help with bird vs window collisions. When applying it I noticed it's a little stretchy so it was kind of hard to keep a consistent as you naturally try to stretch it across the glass. It also doesn't look very pretty. I thought the narrow strips would be less obvious but it looks like jail cell bars on my windows. So the next week I pulled them off to put a replacement item up. I couldn't believe it left I residue on the windows in just a few days. Not to mention terribly difficult to remove because the tape kept tearing. Did not like this product at all

I was hesitant but every morning I was being woke by robins flying into and pecking at the windows all down the front of the house. I put this tape on and they never came back !!
