This sight is very cool looking and extremely inexpensive. BUT when it comes right down to it, it really isnt worth it. It is completely ineffective on gloomy dark days do to the fact that the glass is tinted. I find it almost impossible to zero in the scope. It does work well on sunny days because the tint acts like sunglasses in a way blocking out the sun. It does its job but not very well. Remebr though, you DO get what YOU pay for in airsoft so if you really are going to depend on a red dot sight, spend the extra cash for a better one.
Goes on to rail easy
Has extremely long battery life
Red dot is very bright
Tint helps on sunny days
Hard to zero in
Tint does not help on darker days
All in all, if you really arent going to depend on looking down the sight for every shot, get this but if you do depend on a red dot sight, spend 20-30 dollars more on a better one.
