One flaw, otherwise fine - Leupold DeltaPoint Micro Red Dot Sights 1x 3 MOA Red Dot

It has 8 brightness settings. The flaw? The motion activation only works on the 4 brightest settings. Those brighter settings are useless in poor light. The dot becomes a big red starburst. Other than that, it's slick. Very easy to find the dot. It's as easy as lining up iron sights. It's also effectively a co-witness once you see where to put the front site in the window. This is essential. Thanks to the committee that decided the motion should only work on the high settings, you can still use your weapon after the battery dies from being left on. Maybe they will hire some smart people and fix that.
