ROXANTViper Starscope Monocular Telescope – 10x25 Monoculars for Adults High Powered | Military Grade BAK4 Prism Pocket Scope | Weatherproof with Case, Wrist Strap & Smartphone Adapter

Great for bird watching.

My old monoscope gifted to me was a 5x20 non focusable unit. It works and is easily pocketable. It has a wide view angle that works while wearing glasses and not wearing glasses. I wanted more viewing reach.This Roxant Viper is 10x25 giving me further sight reach while still maintaining pocketability. Bonus is it is focusable! This is far more clear than my old monoscope, I am pleased with it’s lightness snd function. The only downside is viewing while wearing glasses is not optimal. While using this Roxant, I put my glasses on top of my head, not a huge deal. I kinda’ wish the view angle was wider, but thats nit picking. This unit is $21 , its affordable and suits my needs. I recommend this product for a quality to cost ratio. I’m not interested in a larger more cumbersome $80 unit. Just buy this Roxant Viper

I bought this along with the similarly priced monocular from Celestron and Barska along with the much more expensive Vortex, all 10x25. I needed something small for quick and simple looks at targets, or for some nice views while hiking, in situations where a proper spotting scope was unnecessary. After comparing, the Roxant is the only one I kept and I'm very happy with it (Celestron was good too).Some details:The Barska was the only one with meaningfully inferior optics, mostly chromatic aberration. To my delight, both the Celestron and Roxant were close to if not comparable to the ostensibly higher quality Vortex, with the Roxant possibly just edging out the Celestron (no complaints with either).The Roxant mono's ergonomics are very similar to the Vortex, just slimmed down. I actually prefer this. The Vortex is built like a freakin' tank, which is great, but I intentionally wanted something small and light to keep on my belt and to grab at a moment's notice. For this the Roxant is a little better. Moreover, the placement and resistance of the focus dial on the Vortex made it just a little more awkward to use single-handed. Not a huge deal, but again subtle benefit to the Roxant.This of course is not even touching on the price. For $20-25 this is a fantastic piece of gear that I can just keep in my bag or belt without having to overthink it. The Roxant says it's waterproof, and it might be, but I haven't tested that. The Vortex makes the same claim, and build quality feels a little more reassuring, but the Roxant doesn't feel cheap and the truth is if it does get a little banged or beat up and I have to replace it, I can do that at least three times before matching the price of the Vortex... so yeah, great value.For what it's worth, the Celestron had perfectly acceptable optics and easy focus action as well. It's slightly less ergonomic (different traction and finger grooves), but by no means was it uncomfortable or difficult to use. Feels a little less rugged than the the Roxant though. For my purposes I went with Roxant, but if you like the Celestron better and are looking for a budget 10x25 mono I doubt you'll be disappointed.The ONLY critique I have, which isn't even that bad, is the case it comes with definitely does feel cheap. It's a very thin polyester rip-stop kind of material, compared to the Vortex which comes with a strong, beefy ballistic nylon case. With that said, for $22 I'm absolutely not complaining. If you do intend to have this on a belt or in a bag with things that can bump it maybe consider getting a different case; this one will get the job done though, just not super protective.

Product arrived with a loose lense, and would not focus to infinity. I was able to shift the primary lense enough to use it, as it appears it’s missing a spacer inside to retain the lense.as my kid was very upset that it didn’t work, I wasn’t able to return it, but when I contacted Roxant, they offered no help whatsoever. AVOID.It’s a waste of $20.

Roxant viper monocular lets light in but the resolution is low when you look at far distant object and that’s when you need high magnification the most.After comparing it with Carson 7-21 ,The Carson 7-21 appeared clearer at 7x and 8x than the 10x roxant viper! although roxant is brighter but it lacks the resolution. The Carson 7-21 is more versatile and it’s best clarity at 7x to 8x (at 7x the objective lens of Carson gives a bigger 3mm pupil size compared to the fixed 2.5mm pupil size of the roxant viper) and then start losing resolution, brightness and focus control as you go up but still gives a nice performance for its price and smaller objective lens size.The roxant fill from a car dashboard on a hard object inside the car (70cm hight) and became blind with objects shaking inside. Opening it showed how the inside glass broke a thin and cheaply plastic holder easily..! What is the benefit of using a strong rubber outside and using cheap thin plastic pins inside that can’t hold the glass for a moderate hit!.
