Sightmark reflex - Sightmark Ultra Shot Reflex Sight

So after having the sight for a while, I've only been to the range once.. didnt have to adjust it at all and its still holding zero perfect battery life is long. the reflection from where the laser sits is kinda noticable in low light settings, and the brightest setting is to powerful in in darkness, it gets blurry, so you'll never use that.. the battery cap loosens when u turn it on nd off over time, but never came all the way off.. all and all it's worth the money, no real issue..
