Review: Not bad for the money. Would buy again. - You get what you pay for with glass and optics. While this certainly isn’t the best optic in my collection the size makes it very convenient to bring along. I payed around 20 bucks for it and brought it along my backpacking trip through Europe. It took up hardly and space in my bag and provided okay magnification. Quality definitely drops off in low light conditions but it’s still usable. I dropped it a few times and it got rained on a couple of times as well. It still works. 10/10 would buy again to serve the same purpose, a cheap convenient optic that I wouldn’t be heartbroken if it got lost, broken, or stolen.
Review: 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
*by D***R on May 23, 2024*

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.
