Review on Artscape Etched Bird's Eye View Clear Window 🔍 Deflector - 6x6 Inches, 6 in. x 6 in. by Crystal Murphy

The robin attacked the window every day for several weeks in a row. He would sit on the windowsill and peck out the window several times a day, making a mess on the windowsill and on the porch below. Tried to stick strips of carpet on the windowsill, did not help. I hung them 4 days ago and the robin has not attacked the window since. I can't tell if it's the window deflectors or if the bird just went somewhere and found a new window. If it's not the deflectors then it's quite a coincidence that the bird hasn't returned since the day I installed the deflectors. From the inside they look like etched glass, from the outside they are almost invisible. while it works for me. Much luck.
