My wife bought one about a year or year and a half ago. She tried using it and the focus was so hard to turn she boxed it and put it away. I decided to try it and pulled it out. The focus knob was still so stiff it couldn't be turned while looking through the scope. I sent it back to ATN about a month ago and am waiting on it to come back. If it works like advertised, it will be a good scope.
