Any Red Dot User Out There?

Being that my eyesight isn't what it use to be,I have found that the fiber optic dot's on my turkey gun appear as more horizontal marks, than dots,both front and rear sights. I really don't want any magnification,so do not have the need for a scope. I know red dots require a battery,but will carry a spare,just in case. If any one has had experience with the red dots,good or bad, I would appreciate your feedback. Thanks
