I?m hoping someone out there has experience with this product to prevent birds from striking windows:

A friend uses 1/8? cord spaced 3? apart hung vertically in front of windows to prevent strikes, but was wondering about this company's use of monofilament instead. If you have any experience with this product or have strung monofilament in front of your windows as a deterrent, please let me know. Thanks.
