Before I buy a product like this I look at the reviews of similar products and judge the best one to go with. Vortex scored high with 4-5 stars throughout their entire product range. These binos are at the lower end of the product range but are superb value.

Very well built, superb optics for the price point. Not too large as to make them a burden to carry. Good for the causal user to view distant objects when traveling or watching nature. Would be perfect to leave in a car or cabin/camper. Vortex hit a home run with these binoculars at this price.

Use for birding. Lightweight, adjustable, and quality glass.

For a 10x28 Binos these are well worth the price super clear glass. My wife uses them for bird/deer watching, I use them at the range they are durable and rugged. You won't be disappointed.

For the price and what you get you can't beat vortex. These Binos are hands down the best I've ever owned and in a compact take any where size I couldn't ask for more. Highly recommended the diamondback line from vortex not just the binoculars but they're scopes too

Awesome product from Vortex. Great, and compact for when I'm out running and gunning in the woods. Also great for light weight scouting for new areas to hunt.

I typically prefer larger binoculars but wanted a small bino to keep in my truck. I was pleasantly surprised at the clarity of theses binos. I have other Vortex optics that I love but honestly got more than I bargained for with these.

Compact, lightweight binoculars with fantastic optics. Lifetime warranty puts me at ease that I don't have to baby these.

These binoculars are just about perfect for a LE patrol bag. They strike just the right balance between form and function. Reasonable size, excellent clarity, magnification, and field of view.
