Solid value! Highly Recommend!
Five Stars or as I like to say two thumbs up on these 12x50 binoculars. Don’t let the fact that they are made by some lesser known brand hold you back from purchasing them. They’re well worth the price. I like to know how binoculars are going to perform both for distance viewing and close range. So, I’ve provided two pictures to back up my review. I used the included cell phone adapter with my iPhone X to take these pics. The first is a herd of Elk from 1.47 miles away (according to Google Earth). As you can see from the pic, you can easily find and identify how many Elk are there. If you wanted to count tines or gross score a bull then you would want to use a spotting scope. The fact that these binoculars show this much clarity at this distance is a testament to their quality. The second picture provides a close-up perspective of a tree about 50 feet away. The details of the limbs makes me look forward to using these binoculars for bird watching…I can imagine a Mountain Blue Bird perched on one of limbs! One of my favorite ways to evaluate binoculars is to look at limbs and see how distinct they appear. High quality glass will provide sharp edges and clear details as these do. Also, notice how clear the limbs are but the background is blurred…this shows how effective the focus is at helping you define what your looking at. One final point that I want to mention is that these binoculars have a screw mount that enables you to affix them to a tripod or window mount. This is very helpful for extended viewing sessions.

Awesome product
Used for nature watching while on a trip. Great binoculars for the price. Clear and crisp image, easy to adjust. 12 power not a great deal stronger than 10 but that's to be expected.

Excellent Quality in build and in magnification and clarity
These binoculars are of a very good quality. The packaging is excellent. They come with an excellent case. The feel is quality from the structure to the lenses. They have a nice solid feel and a nice weight. I went with the 12x50. As some say, they are a bit more difficult to lock onto what you are looking at through them because of shaking hands etc. due to the magnification. The focus was easy to obtain with the normal adjustment. I would recommend setting them on something that is stationary for looking through them which will help a lot. Using a tripod would be the best. They come with the holder for your phone. I have an iPhone 12 the largest size. The pictures tell all. I was using the chair back to stabilize the binoculars. I was 12 feet away from the electric oven and the clock on it. I have given 2 pictures at 1X on the iPhone. Then I did two pics at 2.5X zoom. They are using the camera with and without the binoculars using the camera holder. I am very impressed with the quality of the lenses and the magnification. If you are looking for these types of capabilities then I would recommend these binoculars.
