Yup,
I have had mine about three months. I don't think it has missed a shot. It does change the point of impact to a degree on some rifles which has changed the way I work up loads. I now try to find the max load with the chrono and then fine tune loads, seating depth ect. w/o it. At that point chrono for es etc.
It has saved time and I can shoot in any conditions and not worry about missing a shot.
