Artscape Blue/Yellow Bird's Eye View Window Deflector 4" X 4", 4 In. X 4

I was skeptical about buying these. We have an aggressive male robin who attacks his reflection in every window of our home....every morning dusk and dawn....just like clockwork. Our home has casement windows with screens on the inside, so he sees himself everywhere. After doing some research, I learned that the bird won't actually hurt itself because he flies at the window feet first. The poor thing can get sick because the exhaustion caused by his daily battles. So, I got a bunch of these and put them everywhere. NO MORE ROBIN! As I was washing the windows and applying the decals, we was flying toward the window, but he would hover as if checking out what I was doing! It has been a week and still no attacks. Sunny days, rainy days, cloudy days...no bird. They are super easy to apply, and actually look nice from the inside and outside. I highly recommend these!!!!

This product *does* really seem to work for me. I have a mixture of the 4x4 and the 6x6 on the windows that received bird strikes, and now I see birds turn when they get close. I did see one graze the window, but not outright hit it -- it was being chased, so it is understandable.The one issue I had with this is that the description of the product, and the product packaging itself, state that there are six in the package of 4x4s (there are only four in the 6x6s) -- but there were only four in the 4x4 package :( I see that another recent reviewer had the same issue.

These stickers are easy to place on the inside of the window. However, because they are translucent and not transparent from the inside, they do block the view of the outside, more like frosted glass, but at least the design is pretty. They have somewhat reduced the number of bird strikes, but enough birds have still hit the window that I would not use them again.

Before we found these, we had birds hitting our back patio french doors on a regular basis. It's been 3 weeks since we applied these to the glass panels and we have not had 1 bird strike. They are literally a life saver!! Just make sure you apply them to the area that the birds typically hit and, if the glass is under a roof (like a patio area), make sure they are low enough that they're in the line of vision for the birds. I am so glad we found these!!

I was skeptical at first..,Not believing what I was reading.Well, I am now a believer. I ordered 2Pkgs since I have four large windows in my living room. My order came in on monday...I put them up right away...Bird feeders at every window around the house...Not one bird flew to the window in 5 days! I was getting at least 5 crashes a day... Seriously, not a one..I did not receive this product free for a good review...It's the honest truth...My bay window I put up 3 stickers in a V shape...the other windows have one or two..i kept mine low in the smaller windows...it's been working great...Now I dont have worry about resuscitating the birds... Happy happy

Still have had one or two bird hits on the window, but not like before...And fairly innocuous, doesn't hurt our view.

I have a large 6ft X 5ft window pane that we couldn’t keep clean because of high frequency, multiple bird strikes. I put two of these 4” deflectors in the center of the window mounted diagonally with a vertical spacing of about 8” and haven’t had a signal bird strike since (about two weeks ago). In fact today, I witnessed a Dove fly up and land on the back of a chair in front of the window. The window is under a 12ft overhang so I was skeptical that the deflectors would work without direct sunlight, but they seem to be working well!

The Amazon description and the actual package stated that there were 6 deflectors in the package. There were only 4 deflectors in the package. The 4 deflectors do not work at all. Don't waste your money.
