I purchased my Aimpoint pro from brownells in Nov of 2016. I have not turned it off since I received it. I noticed a few months back it was very dim even on the brightest setting and I couldn’t see the dot outdoors. I changed the battery and it went back to normal. It’s been 4 months and the same thing happened. The dot wasn’t visible in a dark room until setting 6. Thinking I maybe got a bad batch of batteries I put another brand new battery in it. Now it’s visible indoors again but still isn’t as bright as I remember before.
In a pitch black room the dot isn’t visible until setting 3. Is this normal?
