I found these deep in another post on this site and thought i would give them a try. After ordering them about a week ago they came in today and I just finished installing them on four guns this evening. They were very easy to install, just follow directions and make sure sites are clean prior to starting. I have trijicon sites on another one of my guns and while those are nice because they are "always on", the Nitesiters need to be charged with a flashlight or lamp, but once they are they shine much brighter than the Trijicon. I'll be interested to see how well they last through the night.
By the way I did all four guns for under $13.00 including shipping.
