I loved this sight as soon as I got it. It has 7 brightness settings and you can easily see it on the brightest days. There are 4 reticles: a cross, a dot, a circle with a dot in the center, and a cross with a mini circle and dot. Easily adjustable with the alan wrench it provides. My sight's adjustment was backwards and you had to turn it right if you wanted the thing to go left and vise versa but it doesn't matter.
Easy and fast aiming (much faster than iron sights)
4 fun reticles
7 brightness settings
Easy to adjust
Cool red tint to the glass
My adjustments were backwords but once I found that out it was easy to zero in
