i love it, great for spotting enemy of ID'ing friends etc, if you have a good gun, and you zero the scope you *can* snipe with it (but don't expect it to be 100% ).
it all depends what you are used too, for instance i used to have an air rifle, and did some range target shooting, and thus the thought of not having a magnified sight on my rifles was very very odd to me. That said my CYMA AK has a 556 sight on it
