Coming from nothing but traditional scopes, this scope was easy to mount on my rail system. The dot doesn't appear to be perfectly round but I've only used it in one shooting session. That was to sight it in. Otherwise the optics are clear and in bright light and look like they will be everything that I read about it. After forty rounds with a 308, I'm happy.
Pros: Easy to set up and sight in. Good quality glass and components.
Cons: I felt the lens caps could be a little easier to snap in place but it is probably a matter of getting used to warping them a little when closing.
