Burris Eliminator Laserscope query

A friend of mine has built a long range rifle and is considering buying a Burris Eliminator Laserscope 4-12x42 saving the need to carry a rangefinder into the steep country he hunts. It would seem ideal as the deer he shoots are out on slips in steep bush and if on the move are not in view for long.
Any HBCers used one or know of faults or good points?

I have one and works as intended, range and eliminate them :)

I haven’t used one but I can’t see how they are better than range finding binos. If the shot is that quick I doubt it would be a long one
