Loving mine. Got it last fall I think. Took it ground squirrel shooting in March and ranged squirrels/mounds past 450yds. It rode in the golf bag starting in May, bouncing around in the cart no problems. Could range the pin or flag without the reflectors some have out to 350. Deer hunting this fall ranged deer out to 645 yds and landscape/buildings to 1650. A few folks have had failures but that is the nature of any electro-optical beast. There are going to be failures, guaranteed. How the company treats you makes a difference and I haven't heard any bad news there.
