"This sight is amazing, I have owned mine for over 5 months and have not needed to change the battery, it lasts for ever.

Pros
Runs easily available batteries
long battery life
Great price for an amazing red dot
dot is clear
easy windage and elevation adjustments, no screwdriver needed just use the cap
Comes with riser for hard lower face masks
Changes intensity based on inside or outside

Cons
uses a tiny torx screw to secure battery
uses torx for securing to picatinny

Other than that this sight is amazing
