Well, I do not know anything about March scopes, but I will tell you about the Vortex I sent in to be checked out. I have a Golden Eagle that I thought might be not holding poi just as it should. I was not sure, because the impact point was just off a little, but I thought I would sent it in to be checked out just to be sure. Vortex got my scope in hand on Monday morning at 10:00. I had a new Golden Eagle in my hands on Thursday at noon, the same week. Yup, three days. And I live out in the sticks in South East Colorado where we never get anything fast. Vortex said they impact tested my scope and it failed to hold poi so they sent me a new tested one. Its perfect. That kind of service will make a customer for life.
