The glass? Excellent for the money. Defintiely better than the Monarch ATBs I used previously. However, I have had a cosiderably negative experience with Nikon related to these binos completey unrelated to the optical quality, but to be fair, my situation may have no impact on what you want to do with your binos. See below:
In my case, I wanted to use the Monarch X 10.5x45 binos from a tripod as I had with the ATB binos, and directly asked Nikon tech support if 1) the binos would work with a screw-in tripod adapter and 2) which screw-in adapter I would need. They pointed me toward the Monarch/Action Adapter, which is shown on the Monarch X webpage as a featured accessory. So, after buying the Monarch X binos and the recommended adapter, I found that the center cap that you normally unscrew to use the adapter wouldn't budge. I called tech support to see if I was doing something wrong and they re-assured me that adapter I bought would work with the binos. After exerting more force to try and get the thing to unscrew, the center cap snapped off, revealing a pice of doublesided tape and no place to put a screw-in adapter! So, I now I had a set of binos bought for a specific purpose that failed to meet that need, all because Nikon's own tech support staff didn't know their own product and their webpage incorrectly listed an incompatible accessory. So, that's $470 spent on the binos, another $25 on the tripod adapter, and another $16.00 (that I have to eat) for insured shipping back to Nikon. I'm still awaiting the outcome my request for a refund at this time, as I have no use for the binos, despite the excellent glass, if they can't be mounted on a tripod. Needless to say, there's going to be war if they don't give me money back and try to steer me to a different product.
