Review on Premium Stainless Steel Bird Spikes for Pigeons, Small Birds, and Cats - 4 Feet Coverage (5 Pack) by Antonio Scisson

I have no idea how to assemble this product and how to install it because it comes with no documents or instructions. And without knowing how to use it, I can't rate it well. Update: I went back to the original listing on Revain and one of the product photos was a clue. Well, it's vague, but I get the basic idea. I saw that the bulbous part of the baseplate is on top and you insert the spikes by squeezing them together and sliding them through the holes on the bottom. Once you poke some of the holes that aren't fully open, the spikes will go in with relative ease. You just have to be careful to push them all the way in before you let go of the handle or they'll jump right at you. Assembled, they look quite menacing. I can't wait to install them.
