I have a pair of the older red led ones 10x50 that work great till you try to use them in really bright conditions such as over snow on a sunny day. It still ranges fine but the display washes out. It also has no provision for mounting to a tripod which would be nice but isn't necessary. I have ranged cows out to 1100 yards. I have never used the ballistic function so I can't comment on that.
