Rated 5 out of 5 by Pelt Hunter from Hands down the best... I purchased a Viper PST 4x16x50 a few years ago and was so impressed with the quality, I purchased a second product of theirs to add to my arsenal. The glass is crystal clear every time I put it in my line of sight. All features perform smooth and flawlessly down to each click. This is on my go to rifle for any season, especially predators. Anyone who picks up my rifle always asks where I bought the scope. Thanks guys for putting together great products to aid in our success day in and day out. My glass has a dozen or more harvests with my personal best of 275yds in Just 2 years!!! These binoculars have already spotted a few more prospects the for the up and coming seasons. Works and performs just as well as my scope. Nothing more to add. If you want something that won’t let you down, look no further. Vortex Optics is hands down the best...

Rated 5 out of 5 by Anonymous from Love it Believe it or not, I have bought Diamondback 10x28 to use it as a theater binocular, but this little thing is so great that it got me into watching birds and other creatures which are abound in the Norwegian wilderness, and this gives me so much joy you couldn’t imagine. I have never owned a pair of decent binoculars before, and when I was shopping for this one, I tried similar models from Zeiss and Leica, but decided to go with Vortex because it was substantially cheaper and the image quality appeared superb. The only thing I regret about is that I chose the model with the smallest lens diameter, which naturally makes it not too good for low light conditions, but on the flip side, it is very compact and lightweight, so I can take it anywhere with me when I travel. The design and ergonomics are great. Cannot say it is 100 percent fog-proof, I had some issues with condensation on lenses, but it was only in rather extreme conditions of Brazilian rainforest. Overall, I think it packs a ton of value for the price you pay for it, and the quality is excellent.

Rated 2 out of 5 by XETROV from Poor Quality Control I keep these in my truck for surveillance in loss prevention. They have probably been used a dozen times or less. The last time I used them both of the twist out eye cups wouldn’t twist out. Instead they broke free of the threads and unscrewed. The only way to twist the eye cups out now is to over tighten the eye cups so they will lock to the mechanism that extends. After doing so the diopter adjustment ring is locked solid and useless. Should have paid $50 bucks more for the Nikons.
