I have two older models (10-15yrs) that only reach up to 600yds. I’ve recently started doing some ELR shooting and needed one for up to 1000yds. Came across this one and thought, why not?! It’s a good deal with nice features. Charged it up without any issues. Tested it at 400ish yds and it works well for me. Couldn't pass on a $40 range finder that goes up to 1kyds. The slope function is really handy for accurate ranges over hills and drops in elevation. In my opinion, this is a great deal so far!
