No personal experience with the Burris Signature Zee rings, but I was in need of a solution to a problem I had with running out of windage adjustment on a scope and these were highly recommended by many people. After researching them, I found that based on what I was reading and saw on the video, these rings would be an excellent choice and pretty easy to use. Unfortunately I was unable to get them locally, so I bought Millet Angle-Locs instead.
If you go to the Burris website, there is an excellent video there about the rings.
