if it says "NIKON" on the side, then you know you are getting a good part of optics!! (AT LEAST THATS HOW I SEE IT) Both my new scope and rangefinder are Nikon, and I can't beat them for the price
Hopes this helps.......although I don't know anything about the particular pair of bino's

My friend and I went shopping for a pair of reasonably priced binos , we looked at them all, It came down to price and quality, bottom line ,you cant find a pair of binos for 100 bucks new that are as clear as the ones you just bought, by the way we each bought one.
