I shoot 2 to 3 times a week for a minimum of 90mins each session. Also has belt loop for use as needed. I like the nose button, it took a little getting use to as an anchor point. A bit softer than others I have tried and easily installed. I made sure the open end of the clamp was opposite the slit in the kisser button. Having troubles keeping on my new set up. The inside of the case itself measures about 4.
