This scope is great. I have been using it for about three months now, and it has not lowered it's performance. It is easy to set up, and is very sturdy. The only thing that i would not go with out with this scope, or any scope, is a BB shield. Within a couple of weeks a BB hit my scope straight on. Luckily this scope has a life time warranty, so i was able to get a replacement with no charge.
-easy to set up and sync with your gun
-none that i can thin of, but definitely get a BB shield with this or any scope you are planning to get.
