Best unit around in this size range
This is the best monocular in this size range. We'll made, focus is great, and the rubberized outer covering makes this perfect.

Great for cycling.
This fits nicely in the pocket of my cargo shorts for biking. Has clear optics. Other reviewers said that the front lens fell out and mine did, too, right out of the box. I fixed it with a little Gorilla Glue and it's been fine for nearly two years. Easy to focus. Great monoculor for the price.

Works well, good value
It works well, is easy to hold and has clear optics. For the price it seems very good value. It's very compact and easy to hold. Nice and solid feeling, I don't feel like I'm going to break it accidentally. The case it comes with is functional but nothing special. No complaints really.

very bad quality optic
Horrible glass... yes it's 10x.... But the glass isn't ground well. only the center is sharp and the image vignettes badly.... this basically makes it a tunnel vision effect. eye relief is bad also. Feels like a toy in the hand. focus wheel is really stiff and doesn't quite focus all the way to Infinity.

so handy
Love this little pocket size monocular. I actually keep it in the car door passenger inside handle area. My grandson loves to use it while I am driving. It works pretty well for its small size. It definitely is better than nothing when I need a closer look at something flying over, or If I end up birdwatching somewhere and left my binoculars at home. Good in a pinch.

Premium quality monocular!
It's compact and lightweight, perfect for my birdwatching adventures. The magnification is impressive with clear, bright views, even at dark time. It's easy to carry and use. Excellent value for the price! A must-have for anyone who needs a portable monocular. Highly recommended!

Found Wanting.
Honestly, this thing is cool, yes. It is a cheaper monocular that you can just throw in a bag for a little better view of something further away. So, how does it hold up? Well, it’s a sturdy plastic. The eyepiece feels like a somewhat cheap rubber. I say this because I tried to see if I could fold the eyepiece to use on sunglasses—nope. So, you can’t use it with sunglasses. The magnification: It’s okay. It is decently clear, but really is only clear to about maybe 300 feet, if not a little less. It’s good for birdwatching from your house or at a park, as long as the bird isn’t too far. I’d say the minimum clear magnification is about 20 feet (reasonable for that). I gave it two stars because it feels a mix between somewhat sturdy (main housing) to cheap (eyepiece). The magnification isn’t great, but for a kid or someone who just wants a compact monocular to throw in a bag, it’s okay. I just would say this is worth $10, more like one you’d get at a National Park gift shop. For a hiker or someone needing something more serious, I’d say spend more money for a better compact monocular. I won’t return it, but I think I will look for a better compact monocular.

The front lens was loose inside the tube when it arrived. I pushed it back into place and it seems OK now.
