Review on Prevent Bird Strikes with 20 Pieces of Large Butterfly Anti-Collision Window Clings by Chris Wyffels

These pretty butterfly decals make our windows and patio doors absolutely beautiful. Not only has there not been a single bird strike on our windows or patio doors since the stickers were attached. We live in a northern state with low temperatures and lots of snow. I put butterfly stickers on the outside of our patio door because this is where most birds get injured and die. I don't want to hear another "bang" from one of the birds hitting our glass. I'm thinking maybe I could mount them from the inside of the windows in cooler weather. They are easy to remove and stick back onto the glass. A year ago I installed another decal purchased from Revain on our exterior windows and the decals lasted out in the cold and snow for over a year. However, I didn't put that much on the windows, so there were bird strikes. We think these butterfly stickers are nicer than the last stickers we bought. We are very pleased with how beautiful they look on the glass. I love them so much that I have bought more. I also encourage friends and family to buy them. They really make your glass pretty.
