I love this sight so much, I bought 2! The 33mm Reflex lens gives you the widest field of vision possible so you don't have to worry about the tube of your scope hiding an enemy. The 7 brightness settings come in handy when you're going into a dark room. The battery does loose its strength in cold weather but there's nothing you can really do about that. If the battery does die, and you have iron sights, you can just pop them up and it's like this dot sight isn't even there.
-Different sight styles
-Varying sight intensity
-Easy to attach
Might be a little low for some people, I like it just the way it is.
The arrows showing you which way is up and which way is right were backwards on mine (the right arrow made me go left, the up made me go down) just something to keep in mind. Either that or I'm just stupid.
Lens is VERY reflective from the front side. Bad for night games when people are using flashlights to try and find you.
