Review on 🐦 Window Alert Bird Stickers: Prevent Bird Collisions and Protect Glass Doors - UV Reflective Window Decals by Amber Fox

I purchased this product in addition to the WindowAlert sticker. I bought both brands because I needed different sized stickers for different windows. This product is just a sticker. Also, I'm not sure if this product repels birds as it's just an opaque sticker. Finally, it doesn't come with instructions or product information; stickers only. You want to make sure that 1) the product says "sticker". 2) You want to make sure the decal has a special coating that reflects UV sunlight. This ultraviolet light is invisible to humans, but birds see it as a bright glow, much like a traffic light. I would not buy this product.
