As I age, I find that I need these things more and more...this model is the easiest to use that I have found...the rubber ring really helps. Of course OpticsPlanet's great service and pricing can't be beat.
I have them in each desk, in my fishing tackle box and two or three with my gunsmithing kit.
Pros: Good fit, stays in position, graet value,
