I'll start by saying, I believe you get what you pay for, and quality isn't cheap. I appreciate quality, and am willing to pay extra for it. I am a hobbyist photographer, and have thousands of dollars in fast, f/2.8 professional lenses. I understand what a difference quality glass makes in a lens. The Viper HD definitely feel like they are high quality. Compared to the Diamondback HD, they feel more robust. You can tell they used better materials, and likely better glass. The ocular lenses are beefier than the ones in the diamondback HD. Unfortunately, that's where the praise ends.
The image quality is superb, with very little chromatic aberration and only slight cyan and magenta color fringing in high contrast edges. One glaringly disappointing issue is just that... Glare. The huge ocular lens group is very reflective, and readily reflects light bouncing off my eyes, or leaking in around the gap around my eyes. It's not as noticeable in very bright scenes, but if you're looking at a shaded area, and you have anything bright beside or behind you, you get glare in the image that makes the image degrade. This is absolutely not an issue with my Diamondback HD. The Viper HD is in serious need of large, sealing rubber eye cups. It's like the ocular lens is a big crystal ball that pulls in light from every angle. I tried to show the difference in my images. You can clearly see the large reflections around the edges compared to the Diamondback ones.
Overall, the internal reflections are a deal breaker. Especially when I have none with the cheaper Diamondback HD.
Another issue I have is it seems like the barrels aren't properly aligned. Even when I set the diopter for my right eye, there's just something about the resolution of fine detail that is off. Like my eyes have to strain to put two images together. Maybe I got a defective binoc, but either way, these are going back. Even without the annoying reflections and slight eye strain, the image quality difference isn't worth $300 (150% more) than the Diamondback HD. I wish the build quality was the same. That would make it a no brainer, but even after typing up all these issues, I'm still trying to convince myself to keep the "nicer, more expensive" model. Unfortunately the negatives outweigh the positives. On the bright side, I save myself $500, since I already spent $220 on the Diamondback HD.
No chromatic aberration or fringing like I have with my Nikons.
Good neck strap
Easy to hold.
Not as bright as I had expected. No brighter than my Nikons. This was huge disappointment for me.
Eyepiece very uncomfortable against my eyes.
Had a very hard time using them with my glasses on. I wear bifocals so maybe that made it worse. But for whatever reason just had a hard time focusing while wearing my glasses. And yes I did adjust the eyepieces per instructions for eye glass use. But right now I am thinking I will want a pair that are much brighter than these and with much more comfortable eyepiece.
Very clear, bright image with very small details resolving easily on far targets.
Eye relief is very good and comfy to look through.
Light scatter is pretty bad, if a bright source of light exists near your field of view it creates pretty bad internal reflections making the target object hard to see, probably a coating issue for lack of better internal flocking of the barell.
Focuser is stiff making it difficult to finely focus, this is pretty damn annoying to honestly.
At the end of the day my other pair of Maven 10x42's c1 beat these vipers out in almost every way they are also 150$ less.
I don't stare through them for long periods of time, so I can't comment authoritatively on the glass quality, but the image in general is good.
The size and and weight of the 10x42 is respectable and is a good middle ground between small form factor and magnification/resolution/objective size.
