I know it is not the same model, butI have used a Nikon Prostaff 550 for four or so years. Works well, I have only used it out to about 400 yards, but it has been dead on every time I have checked it. Good battery life, and no reason to complain.
Overall, I have been very pleased with Nikon products. Besides the range finder, I have a pair of Nikon Monarch binoculars, and a Nikon night vision. I Have had nothing but good results with all of the above. Two hunting buddies use Nikon scopes, and do nothing but brag on them. I guess the point of this is, in my opinion, Nikon products are good, and seem to offer great value for performance versus price. YMMV.
