The front sight glows slightly brighter than the 2 rears. The meprolight tru-dots that i have on my other glocks are brighter at night and in the dark.

The orange front appears muddy and indistinct. Not sure why. But very upsetting. Not impressed. Not happy with inconvenience.

The daylight sight picture is poor.

Easy attach and detach. Comes with an extra battery. The cover is loose but for how inexpensive this item is i'm not holding that against it.
