These original blades have greater longevity than the generic replacements. However, they are considerably more expensive than the after market blades.

Way too complicated for me
I purchased this thinking that I would only have to install it "in-line" to an RG6 cable feed.
Anyway, it was more complicated than I thought. Perhaps it will work. Also, I did not know that it requires an exterior source for power. I will have to get a 9 volt battery and then review the installation instructions before this unit has a chance to meet my expectations.
I have a pesky bird that likes to sit on my window sills, then jump up and peck at his reflection on my window pane. So far these bird spikes have discouraged his behavior. I will buy more for the remainder of my windows.
