A five-star product review
I bought several boxes of the Bird-X bird spikes because I happened upon a box of them locally and they worked great. The spikes are translucent plastic and very sharp (be careful). We needed to discourage birds from landing and nesting on the 1.5″ framing around some of our doors and windows. These spikes fit perfectly on such a narrow spot. I attached them with the included epoxy. Once in place the spikes are not very noticeable, although they are not invisible.
I recommend them to anyone looking to keep birds from landing or nesting on horizontal places.
