Almost used to the controls, BUT the dang control button needs to be a lot bigger. My fat fingers don't workie too good with the little button. Went to the indoor range and started at 25 and then went to 50. Holding the dang thing still whilst trying to maneuver the zero function was a pain. Gonna read more on it and go to the website to see what I was doing wrong on the functions. Me and electronics do not get along.
