Read the reviews, decided I must have one. Watched on YouTube all the videos how to install and actually did a good job. It worked! Maybe I was too careful and took longer than I expected but I did not want to foul anything up. After I got everything completed , stated to have buyers remorse when I really got to thinking of the price I paid for what is basically a cat laser. I'm not sorry I bought it BUT most likely would not do it again.
Pros: Very cool, helps with sight alignment
Cons: Too expensive for it's own value . Not as easy to install as indicated.
