I love this monoculars. It transforms my Galaxy S5 into a 10X optical camera, and does a good job. It is light weight and easy to use. The focus seems to be sharp, the button is easy to reach and functions very smoothly. For the money, it is a great way to convert your camera phone from a wide angle optical device to a 10X optical device. I would recommend it to anyone. I picked it because people gave it high reviews, and I agree. I give it five stars also.
I was searching for an affordable high quality monocular and stumbled upon this telescope 10x42 High Power Monocular and I must say that I am very impressed. I use it with my Samsung Galaxy S8 Plus to zoom in and capture very nice images from about 1km away. I carry it with me in the car daily. You never know when something worth viewing will pop up. Let's hope it stands the test of time.
The monocular is awesome. The view is clear, the magnification is amazing. I bought it for bird viewing on the trees and on the water, and it's great for the purpose. It's small and compact and easy to use. It came with some accessories, which I haven't explored it. It is so much better than the more expensive binoculars I bought from Target.
