I used a red dot for 1 season. I never had battery issues and could see my bead under the mount. The problem I ran into was it got knocked off zero and caused me to miss a bird. The only thing that hit that turkey was dirt because I shot about 2 feet low. I also didn't like the extra weight.

I understand you are asking about a regular scope, but I think the things I didn't like about the red dot could apply to a scope.
