I found my first flaw in my 507c v2 today.
Shooting under a shoot house roof to outside target in the sun my dot disappeared. I switched to manual and the dot brightened just fine.
Later I went back to auto while in the sun and the dot worked just fine.
I went back under the shaded roof on auto and the dot disappeared.
I came to the conclusion that it was reading the light under the roof and dimmed the dot when it needed to be bright for an in the sun target.
My first thought on that is this happening to a LEO when encountering the same lighting scenario, could lead to a confusing moment when you need the dot and it's neither broken nor there.
