I have owned several Nikon scopesover th years on hunting rifles, and purchased a Nikon Monarch X about six months ago. I dig the scope, worth the money. I had heard several horror stories regarding their service center though. Well three weeks ago I noticed what appeared to be oil droplets on the inside of the lense at low magnification. Sent it into the Nikon service center in California, they sent me a new one within 10 days of receiving it. They were definitely very easy to deal with, they returned the new scope via UPS two day, and the warranty service was no questions asked. Very good experiance.
